In the next week or so, we'll be seeing the announcement of at least 4 lenses, an EF 85mm f/1.4L IS as well as three new tilt shift lenses, a TS-50mm f/2.8L Macro, TS-90mm f/2.8L Macro and a TS-E 135mm f/4L Macro. We'll also see the EOS M100 mirrorless camera announced around the same time.
We have seen mentions of a new entry level Rebel being announced, but we don't usually hear too much about those.
Beyond that, we aren't going to be seeing new Canon DSLR until early 2018. We've been told that there is likely going to be a “shakeup” as far as prosumer APS-C DSLRs go. The source is trying to find out what the “shake-up will be”, but I think by the time 2018 rolls around, both the EOS 80D and EOS 7D Mark II are going to be ready for an update. Canon cannot wait 5 years again for a sequel to the EOS 7D Mark II.
We should also see our first 4K APS-C camera from Canon in 2018. Whether it is in mirrorless or DSLR form remains to be seen.
The same source says the roadmap shows a replacement for the EOS 5DS and EOS 5DS R coming in 2018 as well. It's expected by the source that Canon will amalgamate the two high megapixel bodies into one model. Nikon did the same thing after the D800 and D800E, as we only saw the D810.
What was interesting is that a “professional EOS-1” is said to be starting in-the-field testing in 2018. That doesn't mean we'll see a new body next year, but 2018 is an Olympic and FIFA World Cup year, which usually (but not always) lends itself to some new prosumer/professional gear.
There was no mention of a full frame mirrorless camera from this source.
