I'm thinking that the 70D and 7D2 will be too-little-too-late.
Because historically Nikon never trailed Canon did they? They never had to catch up with anybody else?
Both Canon and Nikon seem to be in No Hurry to introduce Pro Level APS-C/DX cameras. There are rumors that the 7D2 will be available in 2014, but the are no rumors about the Nikon D400 ever being announced, zilch, nada, nothing. Until Canon pre-announces the 7D2 it's just vaporware.
So that leaves APS-C/DX shooters looking at something that isn't Canon or Nikon.
