Possibly 145 million at the price tag of $99.99/€99.99/£69.99/¥12,000 (or lower).
Sony has just released the new 90000 model with integrated power adapter in Japan. With the way that Sony keeps improving PS2 and promoting the 40GB PS3, I won't be surprised to see Sony releasing a 720p/1080i upscaling PS2 in the near future. If that happens, PS2 sale can easily go above 150 million.
It (PS3's market share) might hit 30%, but definently not more. ~ Neo
