I already responded to them, but I'll do so again just for you.
amd's core business is cpu, with 10-20% max in graphics. they bought ati to enable them to do more with their cpu (mission accomplished), but it's unlikely that they'll ever be primarily a gpu/graphics card company. nvidia, otoh, has no chipset business, no cpu business, and in fact is basically a gpu/graphics company that writes kickass software as well. they are pretty close to 100% gpu related, their tesla lineup, cuda, etc are all geared towards this. so if nvidia has ~ $2 billion in the bank to fight daamit and daamit has ~ $2 billion to fight nvidia AND intel, nvidia has a dominant position.
none of this changes that nvidia dropped the ball this gen, and it appears that amd is not letting their foot off the gas for next gen either. just keep in mind that it took nvidia a LONG time to achieve their favorable market position, and nvidia will need to continue to struggle at 28nm as well probably before we'd really have a sea change in market perception re consumer graphics. Also, as mentioned, nvidia is still doing many things on the software side to keep them in the game, and gtx 460 is a clear winner. they will swallow their pride for now as intel did in the a64/p4 days, and use their enormous cash advantage to regroup and refocus for the next round. this sort of thing happens in business/sports/life all the time, one team gains an advantage and it forces the competitor(s) to re-evaluate their (failing) strategy. It's not a guarantee that NV won't continue with the fermi model of larger/hotter/slightly faster, but I do think that they'll end up getting a 2nd vendor for 28nm (if not GF then someone else) and they'll probably be quicker to market going forward with a more consumer-friendly gpu like gtx 460.
edit: keep in mind, this is a game that amd is unlikely to win in the long term. if nv gets too cheap then intel buys them. if amd gets too dominant in the consumer gpu field, intel can cooperate more aggressively with NV as a counter to amd's rise. For years it has been intel >>>nvidia>>>amd. now it might be more like nvidia>amd but intel is still killing both of them. jhh bit off more than he could chew with his "whoop ass" comment, but as mentioned earlier re xfx & nvidia hurt feelings can quickly get forgotten when there is profit to be made or a competitor to be thwarted. and no, i don't think that i've ever seen thwarted used in a sentence bofore.
