I can't believe you people are still trying to kid yourselves the PS3 is in any way in the same boat as the PS2 was. Do these fevered delussions never cease? Optimism is one thing. Excitement at outselling the 360 is one thing. But this is just pure blind insanity.
Even if we were to buy into your logic and assume the Ps3 will sell 115million just like the PS2 has thus far, then by your logic the Wii will sell 250million units if not more in the same time.
