Come back to us when the 360 hits the 120 million mark, because that's the number of PS2's sold thus far.
The PS3 sold more in its 1st year than the 360 did in its own first year. It did it while competing with the Wii and 360 (360 had a year alone! and Wii was a smash hit) AND being the most expensive console by $200 AND including a high-definition format whose continued relevance was in question until just months ago. That is one good position they have forged for themselves, and no one can deny that there are better things coming. 2008 will be the year of the PS3.
