From the sound of it, I'm afraid they put all their eggs in the MP/FPS numbers. I mean, after all the high ISO performance was never a selling point in the original 7D, it was always the 18 MP/8 FPS that sold the 7D for years. I don't think they are about to change that formula now. That means anyone interested in low noise should either consider a 5D Mark III or even the 6D but don't count on the 7D mark II to fill that void.
While I'd love to see better DR in a new 7D, I must agree with this sentiment as well.
I own both a 5dm3 and the 7D, and the cameras serve very different purposes for me.
And let's face it, given Canon's recent pricing strategy, if they announced a 7D with +2fps, +2MP, 5Dm3 style DR, and even the same AF system it has now, it would likely be upwards of the $1,700 it currently costs.
I'm hoping that if the 7Dm2 replaces the 60D, that will keep it's price point below $2,000. I'd love to see better DR, but if Canon gets too crazy in that regard they risk eroding the sales of the FF lineup.
But I still think this camera is a ways off. AF is still the second best in Canon's line (5Dm3 and 1DX at #1), and the FPS is also #2 (1DX). There's still not a ton of room for improvement that would warrant people such as myself to upgrade while keeping the price low.
My guess is announcement in third quarter of 2013... maybe even later.
