I can't see the 7D mkII being a FF... it could not really be a replacement then, but a change!!!
What ever happens, i just hope for something new this summer, whatever is announced it will hint as to what else we can expect!
BRING ON THOSE ANNOUNCEMENTS!!!
+1. The 7D has its own place in the EOS family, and it has been/is very successful. And it was introduced less than 2 years ago. A true second-generation 7D would remain APS-C - and compatible with EP-S lenses (like the 10-22 and 17-55 as CR points out).
I note that 7D rebates have just been introduced. What does this suggest relative to this 7D rumor?
