So does the 7D line live on or just get replaced by the 70D?
Depends on the 5DIII price that will be announced tonight.
If it's $3500, then yes, the 7D line will live on a happy life for a couple more years.
But if the 5DIII is announced at $2699 tonight (which is my bet), then expect the 70D to replace the 7D this fall as the top-of-the-line 1.6x model - with 22mp, 19 AF points (or more), 6fps, and 100% viewfinder.
All that for $1299. Let's see who will miss the 7D then.
Well, that sounded good until you got down to the 6fps.
