First of all, this is NOT a rename. It's a new chip/architecture, not G92 renamed 395105138 times

Second, it all depends on the pricing! The 3870 and 4870 were priced in the $199-299 range MSRP. The 5870 ended up being priced in the 400's.

Now if they make the 6870 back in the 199-299 range, and make a single GPU 6970 in the $400+ range, it would make a lot of sense and this wouldnt be a big issue. And if Cayman is as strong as people say it is (5970 performance in a single GPU), then it would all make sense!
