It all depends on how much XB360 will widen the gap this Xmas: it has still little room left for price cuts, while PS3 still has a lot, so, while this Xmas XB360 is going to rock and most probably will sell very well for the rest of its life, we still have to see PS3's full sales potential, the cut to $300 will be only the beginning: but barring miracles, PS3 won't have a chance to be 2nd before Xmas 2009. Anyway PS3 won't be able to catch Wii, not for the next 4 years at least, maybe it will catch it if it will keep on selling acceptably more than two years after Wii's sales end.
@Ender:
Retailers will give to PS3 and its games the shelf space justified by sales, they still give space to PS2, that now is selling less than every other console commercially available (but not bad at all). If Sony sticks to the 10 year plan developers won't be disappointed at all, like they aren't with PS2, obviosly PS3 must exceed 50million user base by 2011 end for this to happen, but even at the current sales rate it's not difficult at all. And again, 10 years PS3 life doesn'mean that PS4 will be released 10 years after PS3, it will happen very unlikely after 5 years, most probably after 6-7 years.
