As a 7D owner, am curious for input on if I should wait for a 7D Mk II or just go for the 70D. The 70D does have some interesting features, especially the highly touted AF system, but I worry if I upgrade now the 7D Mk II may be far superior with the same AF system, dual DiGiC 5s, and probably even higher FPS shooting (as a sports photographer that's important!). While I can wait, I can't wait forever. Probably til the end of the year? Anyone know/think they know when the 7D Mk II will come out?? Should I wait?
