Several things here
1. Canon are not stupid they have been around for a long time and are the market leader - they want it to stay that way
2. they are clearly addressing all the concerns of the FF crowd me included
maybe not as quickly as everyone would like but I think this next round of products are going to pretty awesome.
3. They most definately have noticed the EVIL / mirrorless competitors savaging the bottom end of the DSLR market. I fully expect they will respond with something here that knocks the competition out of the park. Everyone in the mirrorless arena talk up APS-C sensors as being huge, cannon are already all over the APS-H tech, might we see the rebirth of APS-H in this format? The thought of an APS-H mirrorless at a decent price, with and EF adaptor?
4. I seriously doubt canon are going to just drop the APS-C crowd or let it die I think they will come out with a stunning high end APS-C. The build of the current 7D is great if they use the same body and beef up everything else and call it a 70D does it really matter? they do need to rationalise the APS-C line especially with the mirrorless compacts eating into that arena i mean 7D, 60D, 600D and 1100D with a price gap of what $700 seperating all of them? somethings gotta give here.
anyway thats just my thoughts on the subject
Canon bring it on!
