Depends on your point of view. Those with unstabilised lenses would obviously agree, but long lens shooters would prefer in-lens. Personally, I'd like to see IBIS as it'd make some of the unstabilised primes I want a lot more appealing - and there in a nutshell is why Canon will surely introduce it soon.
I think Canon might be quite relieved to get away from the 5D Mk1, 2, 3, 4 straight-jacket that predetermines a certain feature set. It's a bit like the movies Jaws 1, 2, 3 etc with a predestined story-line. Nice problem to have tho
Throughout this thread people have fallen into the trap of thinking what's important to them is important to everyone else. Canon knows what they're doing and every feature, or lack of, is deliberately and carefully considered. I'm sure that if we sat in Canon's board room (overlooking the warehouses full of DSLRs and EF lenses) it'd all make perfect sense. The EOS-R is the first of what will become a long and comprehensive line of cameras appealing to a wide range of users at a wide range of prices. It's just one camera, pitched into the popular upper-middle sector. I don't think it's realistic or meaningful to draw too many conclusions about what Canon is capable of or what we'll see in the (quite near) future. But it's a promising start IMHO.
