There have been a plethora of rumors... and more leaks than I've seen in years regarding a new camera launch! It's been Canon's worst kept secret! (More leaks than the White House, Senate, House of Representatives, FBI, CIA and Pentagon put together! 
)
Follow the link above for more info....
But many of the rumors appear wrong. First, it looks like there will be three adapters to allow current EF/EF-S lenses to be used on the new full frame mirrorless camera, which will be called the EOS R and will be 30MP (like 5D Mark IV). I'd be surprised if it were only $2000.... but haven't seen any priciing yet. We'll have to wait until tomorrow.
The reason there are three lens adapters is interesting....
- One adapts EF-mount lenses to the new RF-mount.
- Another does the same, but also has a built-in drawer for drop-in filters. This will be very cool when adapting some of the lenses like the EF 11-24mm or TS-E 17mm, which are difficult to use with filters due to their convex front elements. It also will allow use of smaller, far less expensive filters (I'm guessing 52mm or 58mm) on a lot of lenses that now use 77mm or 82mm.
- A third adapter is specifically for EF-S lenses. That surprised me, but the EOS R apparently has a "crop mode" that allows it to use the APS-C crop-sensor lenses too!
The EOS R appears to have a 20mm lens register (distance from the lens flange to the camera's film/sensor plane). This is nearly an inch shorter than the 44mm or so used in the EOS/EF-mount, and the reason that the adapters are needed. The RF lenses native to the R will not require an adapter and initiall there will be four of those available: RF 35mm f/1.8 IS STM Macro, RF 28-70mm f/2L USM, RF 50mm f/1.2L USM and RF 24-105mm f/4L IS USM.
Due to the 20mm lens register of the full frame camera, I don't think it will be able to use EF-M lenses, even in crop mode. There aren't a lot of those lenses yet, anyway (and there are rough equivalents of all or most of them in EF or EF-S anyway). But, who knows! Maybe Canon has some trick up their sleeve.
A BG-E22 Vertical/Battery Grip also will be available for the R, doubling the battery capacity of the camera (which will use the same LP-E6N as 7DII, 5DIV, etc. Also can use LP-E6, with a few minor limitations).
There are a lot of other really cool and interesting features, including what looks to be an amazing auto focus system (over 5000 AF points... pairs of pixels embedded in the sensor and nearly the entire image area covered... and -6EV capability!).
Frankly, for my purposes I'll need to stick with my DSLRs for the foreseeable future, in large part due to the 2500+ shots per charge I get with a pair of LP-E6N. Mirrorless have to power up a lot more stuff contiuously while in use, so none are anywhere near as power-efficient as DSLRs.
Even so, I can hardly wait until tomorrow to learn more about the new camera!

Film has moved to the vestige of 'art'.
Canon has already ditched a lens mounting system once. Will they do it again?

John_SD says "I don't have much money invested in DSLRs or lenses. " So what did you spend your money on, or is this a new thing for you? How much skin do you have in the game? If you are a newbie I would agree that careful investment in MILC tech is a good idea, but don't underestime the enormous market out there in DSLRs that the major manufacturers have to support and show respect to.
The thing is this is not an 'all or nothing' situation right now or for some time yet. I have already agreed that this is the beginning of an evolution from DSLR to MILC, that was pretty obviously coming for some time, but both Canon and Nikon have been demonstrably wary of jumping in with both feet - they have left that to Sony and Fujifilm in particular. Canon are expected to release more DSLR bodies and are supporting the EF mount so they have not suddently switched platforms and left the market hanging, specifically because of the investment of millions of customers throughout the world - that would be poor business strategy. In support of the EF situation I only have to look at the crop of quality EF lenses that they have just released in the last few months - they, like bodies, take time to develop and they aren't just going to drop them tomorrow, for a start they are still selling well they want to get their money back, and lenses last for a very long time.
The comment about film being "a vestige of a bygone age" is simplistic, dismissive, disrepectful and demonstrative of those who see photographic technology as an end in itself rather than a tool to achieve a result. I suggest doing a search on Google for professional photographers who shoot film, and while we are at it read the Time article http://time.com/4646116/film-photography-inspiration/ . These are successful, high-status photographers who are much sought after and get very well paid because of the quality of their analogue work.
As ebiggs1 has said it is most likely connected to art. Well, the news is that photography is a marriage of technology and technique for a myriad of purposes and art in its various forms is a huge part of that. Most experienced photographers would say that of the two, technique is the more significant a photographer who knows his equipment and the right skills will always beat an unskilled photographer with the latest tech.
Supporting analogue technologies is recognized by a growing list of film manufacturers including:
China Lucky Film - the market in China is growing massively
Cinestill
Ferrania (included the Solaris brand. Shut down in 2012, but as of 2017 efforts to revive it are underway)
Fujifilm
Ilford Photo (went bankrupt in 2004, but reorganized and restarted production)
IMAX
Inoviscoat (An Agfa spin-off that manufactures film components for other brands, including Impossible Project)
Kodak
Lomography
Polaroid Originals (was Impossible Project)
Rollei (repackages film from other sources, including aerial film manufactured by Agfa-Gevaert in Belgium)
Tasma
and the list is growing... there are even companies starting to make new film bodies. They would not have got past the business case stage from investors if they could not prove a viable market.
I used to shoot film professionally, though I have been a digital (professional and non-pro) user for 18 years now, but I recognize the value of the medium and I am not arrogant enough to dismiss those who still see value in it. I own about $50k worth of digital gear, including MILCs, but I have no intention of selling off my stuff in a panic. Good luck to those who do.
