Honestly?
I think the most likely scenario is the same old - ATi is having yield problems.
This was the reason NV30 had such a huge delay, and I wouldn't be surprised at all if it's the reason ATi keeps pushing back R520 and we haven't seen much of it. Some industry "insider" rumblings have even said R520 is going to be ATi's NV30. I don't know if I believe
that, but I think it's very possible that yield issues are what's holding them back.
One on hand, that may mean it's a very ambitious GPU design, but on the other hand, if they can't get it on shelves, ambition means squat.
I think if G70 shipes first with no answer from ATi, ATi is going to have a rough go round next generation. That's textbook Nvidia though - they're aggressive like sharks, and if they smell blood in the water, they'll take advantage of the opportunity.
