Can't canon just design a LP-E6 II....same shape, better internals and work with any camera that takes the LP-E6
+1 I have 7D and 5D MkIII and would hope that LP-E6 can continue in 7D MkII. I expect that a LP-E6 II, whatever that may be, would not be compatible with 7D and 5D MkIII, regardless of the chosen shape. I have 5 LP-E6 copies today and a 7D upgrade to 7D MkII with LP-E6 compatibility would be very attractive - and makes sense!!
A dual Digic 5+ processor is a logical choice for the 7D MkII, although I get along fine with 8 fps with my 7D.
