Given AMD's previous paper launches, I wouldn't doubt it if this is the plan. They know that they need Hammer to compete for mind share, but in terms of revenue, it will be a long time in coming. And that's assuming they don't run into additional problems along the way.
I saw these numbers yesterady... I was more than a little skeptical because it would result in AMD having 27% MSS by the end of Q4, and given that they're currently at 15%-ish, that seems like a long hard road to me. Quite frankly the numbers seemed more like "optimistic best-case scenarios", a la a certain poster on the SI thread, than true projections...
