Go visit Japan and after you seeing the humongous amount of PS2 games in the stores, you will realize why PS2 is still selling, at a price point not too far from Xbox360 Arcade (16000 yen vs 19800 yen).
Besides the top selling new PS2 games like Persona 4 (301K Week 13) and Super Robot War Z (419K week 2), the Japanese developers would rather port PS3/Xbox360 games to PS2 (Dynasty Warriors 6, Dynasty Warriors Gundam), but not to Wii, that should tell you something.
It (PS3's market share) might hit 30%, but definently not more. ~ Neo
