I don't believe that anyone will beat the PS2 but I don't think that anyone really wants to. The Wii will sell over 100 million and the DS will beat it but it's a handheld divice so it doesn't compete with the PS2. I think that nintendo will stop selling the Wii before it is reduced to less than $100 which will probably be in 3 to 4 years more years because Nintendo is about making a lot of money on their products and when they are making less than $10 on the Wii, there will be no point in continuing. Plus Nintendo will learn from Sony that it is not a good thing to have two products on the market competing against themselves (ei. PS3 and PS2)
