For the most part, yes, that's exactly right.
I can tell you this:
If Kepler comes out 15-20% faster than my GTX580s, I wouldn't sell the 580s at a loss and buy Keplers for $550 either.
Just as I presume not many people with 6970s sold them at a loss to buy 580s, or people with 5870s sold them to buy 480s. Unless they wanted to use 3d, CUDA, or PhysX, why would they?
Of course you're assuming Keplers won't be much faster than 7970s, which we don't know yet.
