I think the two main reasons the PS3 will easily blow past GC's (And eventually even the 360's) numbers are as follows:
1) Price cuts. If the $399.99 PS3 rumor is true (Which all signs point to 'yes'), then sales will pick up greatly from that alone. Whereas the GC was never expensive, the PS3 will benefit far more from price-cutting.
2) High profile games are not yet out. I'm still dumbfounded people are naive enough to write off a system whose top 3 franchises (GT, MGS, FF) have yet to release. Couple that with some new IP's that might take off, the GC was never in the same league as far as game diversification goes.
