they should just present something new and not just relabeled sensors and smaller camera bodies. why still no affordable mirrorless?? could easily dominate the market but yeah...
If it could so easily dominate the market, then why aren't the other mirrorless offerings dominating?
I think that both canon and nikon are on the right track, they know that if the winds turn towards mirrorless they could easily bang a few models out there. But in the meantime, focus on the side of things they know they have a market for - like video and mirror based still camera's. then see what happens.
Unfortunately though, as most have pointed out here - with the emphasis for mirrorless being smaller and lighter unless you want to live in a world where your focal length maxes out at 135mm, then this new thing will be a niche market at best. The only other way this goes down is for a mirrorless system to be designed that DOES NOT require current dslr users to ditch all their lenses. Create a mirrorless body with the same size as a current slr, and keep the damn mount the same - EF lenses...no silly quality killing adaptors, then mirrorless may have a chance because it will be a lot more viable for pro work.
But ---what's the point then? why recreate the wheel? Other than draining batteries faster, not seeing much reason for mirrorless - it's not revolutionary, it's not even evolutionary ---it's kind of a backstep when you consider all the glass that goes into the garbage
I don't bank on that though.
