I think it is clear Canon have created a demarkation of the xxD to allow for a top end model, in the same way we have xxD controls on the 6D. For this reason I'm pretty sure the new 7DII will have 'top end' control interface and be about 50% more expensive than the 70D. This would put it just below the 6D: to use current UK prices including VAT - 70D = £858, 6D = 1379. Add 50% to the current 70D price and voila ! - you have £1287. Job done for Canon.
+1 hope your right about that.
And if your willing to go grey that would probably be about £1094 (70D - £729 grey)
Interestingly the 7D is currently at £1029 (bricks and mortar) making a 7D2 at £1289 look like a real bargin even with quite modest on paper improvements say 1 stop better ISO performance, 5D3 quiet mode and AF without the jitters. I say on paper because I think that in the real world that would be a hell of a good camera!
On the other hand....
First pic of Nessie taken with a Canon 7D2.... Scientists are sceptic about the authenticity of the 7D2
