No, and Killzone 2 arrives at the end of next month (February), so how the hell is that long enough to move any consoles on Februray? Anyway, KZ2 will probably give PS3 a 40% hardware boost at best which won't be enough to outsell 360 for a single week.
For the whole year? a $300 PS3 could do it, if in time for Black Friday at the latest.
