Compared to 360 last year, PS3 is selling slightly worse in the US, and slightly better in Japan and Europe, so I dont know why you keep on continually posting about how "Sony is teh doomed".
Sony is selling a lot worse actually, it's not just slightly. Look at the numbers: MS has been at 2.4 million after the first ten months, and PS3 is at 1.74, according to NPD. That's a 38% difference, already quite substantial IMHO. It's selling even worse than the first Xbox; and also remember that the 360 has been supply constrained for quite a few months.
But the more important problem is that you have to look at PS3 sales within a context, and that is two competitors continuosly selling far better then them. Thus the gap is increasing, and the difference between monthly sales will keep on getting bigger as the Wii and the X360 drop their prices, and gain better publisher support for their larger installed base.
Sony is not yet doomed, but the chances are increasing with each wasted month. We cannot tell when that certain moment arrives, probably wouldn't be able to tell even years after - but it's getting closer for sure, the way they're doing right now.
Another important point might be that the well-known and highly successful first/second party franchises aren't guaranteed to move hardware as well as they did with the PS2. They've sold a lot of copies precisely because the PS2 has ruled the market, but the customers aren't neccessarily loyal to these games. It might be that a lot of people only bought GT, MGS and FF games just because they've owned a PS2. If it really is the case, then these franchises might also be unable to turn the tide for Sony.
