Hmm, what's wrong with the LP-E6 battery? It was kept for the 5DIII. While I doubt I will buy a 7DII, if I were too, that would be a pain - given a current collection of 8 LP-E6s, used across 3 bodies.
++1 First thing I thought as well! Say it isn't so!!
Nothing wrong with the LP-E6 Battery!! I carried the same batteries with the 5Dc and 30D/40D. Then I got the 60D with the newer battery. Now I finally have battery continuity again with the 5D3 + 60D and if I got a 7D2, I would carrying two different batteries
again. Come On Canon!! Aaaargh!

24+ MP on a crop sensor might be scary.
Hate to have a bad attitude here but based on the pricing from Canon this year, they will probably initially ask for the moon for the thing. Obviously from the deals we are seeing for the 5D3 now, the initial retail price is very inflated.
