Yeah... you are right... that can happen but that was the worst case scenario... I think MS can fix the things before the release and just have a few months of bad supply.

We can only hope, but it looks like their solution is to downclock.

The clock rate of the gpu part was never stated by AMD/MS. Here is a theory just as good as any other theory (or probably even a better one):

Knowing they had a weaker gpu by design choice than the PS4, they very likely started with a higher clock to offset fewer compute units. When the higher clock caused problems (not with esram yields, there are no yield problems with large numbers of ram banks, ever, due to inbuilt redundancy) , they downclocked to "normal" 800MHz which gives the 1.2Tflops rumoured around. So this whole "downclock" thingie already happened months ago (at the time the whole "yield problem" gossip started popping up - go figure!)

Too lazy to read up, but wasn't the Flop number at 900gf now?  Which is quite paltry.
