Wasn't the wording "until the end of the year"? That wouldn't exclude the possibility of seeing something in Q4.

As much as I like Titan (I have two) - it's "only" 30% faster than the 7970 GHz while consuming even more power. If AMD manages to gain 40-50% on the 7970 GHz (which would be little to normal with a new node), they would be comfortably faster than Titan and considerably cheaper to produce and sell.
