Looking at the Canon line-up, the 7D will be the top of the APS-C line up. I would hope that Canon would take the opportunity to build a great camera, something significantly ahead of the current model and the 60D and where they will take the 70D.
The big question is how close to the 1Dx will Canon take the 7D M2 both in features and price. After all the 5D M3 started in the $3,000s - could the 7D M2 with great features be priced there?
Would you pay $3500 (or so) for a mini-1Dx in APS-C format?
