The Ps2 was always going to have the most hardware sales, no matter how many things it did wrong with the hardware. Why? It all dates back to the N64 and Psx days.
Sony struck a gold mine with the Psx, and now they sit comfortably for the next couple of generations of consoles (including the Ps3 me thinx). Because they have won the consumers trust in a console that has the most varied and high quality games.
With so many people buying a Psx, naturally the Ps2 is going to sell, especially considering it has a DVD player installed (which was highly on demand at the release of the Ps2). Which makes me think if the Ps3 is going to come built with a DVD burner
It's a no brainer. The Xbox and GC will never catch up to the Ps2's sales. But each console does have its good/bad points. Which is why I bought all 3. So as a gamer I can choose which games I want.
