It's not going to be aimed solely at sports and nature, it is going to be what it is today - the flagship APS-C camera in the Canon lineup - only better - regardless of what you typically shoot. The 60D is a really nice camera but it isn't a 7D nor was it ever intended to be.And the 60D will be going the way of the dodo according to the rumor
"The current 7D will continue for some time and surplant the 60D, when the 700D comes along with increased specifications."
Which means there is room for a higher level (and pricier) 7DII, costing a similar price as the 6D, but aiming at a different market. Then they'd have a nice sports/nature camera for $2k, a nice landscape/portrait camera for $2k, and a nice street/wedding/etc camera for $3k. And if you can't afford those, the 700D is <$1k, and the current 7D will probably drop a few hundred bucks and be in the $12-1300 range (which is where the 60D retails)
