Of course, they sold 87K 360s in Japan by the end of 2005 and PS3 has already sold 490K in that same amount of time.
For me, the interesting question is, "how many units did each console have to sell before pent-up demand was satisfied?" I, as somewhat of a guess, estimate that in NA, pent-up demand was met for the 360 in March of 2006. For the PS3, it was January 2007. (The PS3 may not be at that point in other regions, (Japan, EU) so I'm limiting this to only pent-up demand in North America.)
From the VGAcharts, it looks to me like the PS3 met it's pent-up demand with less than 1M units sold in NA, while the 360 met it's Pent-up demand at almost twice that. I think the ebay tracking correlates with this as well.
None of those figures should be taken as accurate, it's just a wild estimate and speculation. Still, it's hard to escape the conclusion that the pent-up demand for the PS3 was lower than what most would expect, and lower than it was for the Xbox360.
