You can\'t really base PS2\'s victory on numbers, against two consoles that are not even out.
Just because, yes, the PS2 has 15,000,000 units sold, this does not knock Nintendo, or Microsoft out of the ring. A lot of people already have PS2\'s(and a lot don\'t), and some of those people will either buy a Cube or an X-Box based on what kind of titles they want, that they can\'t find on the PS2(if I were them I would buy a Cube, because it offers awsome titles such as Luigi\'s Mansion, RS:RL, and Eternal Darkness).
I\'d say Cube has won in this respect considering ther are a lot of PS2 fans who hate the X-Box. But, there are a lot who like it, so in the end, you have to look at what more gamers want, as time goes on.
