Nintendo is the only gaming company that will last the test of time. Sony and Microsoft will die, just like Atari and Sega did. It's already beginning to show. Sony and MS are making motion controls to keep up with Nintendo, but they're barely keeping up. Nintendo is always at least one step ahead, if not in technology then in innovation.
Microsoft is showing it the worst. With the loss of Bungie they're in deep shit. They haven't got many great first-party developers. They've almost completely abandoned PC gamers like myself, though Fable 3 is a nice addition to the list of exclusives that the 360 doesn't have. Xbox Live is old fashioned now as well, with Steam doing everything that XBL does, except many times it's better. I foresee Microsoft making one more console, then dropping out, and you can quote me on that.
Sony is doing a bit better, but it's too late for them. They just recently started turning a profit, and the PS3 is selling pretty decently, but this doesn't change the fact that it happened too late. The damage is already done, and Sony won't be able to recover it any time soon. I predict that Sony might last for a good while, but they will never be a major player like they were the last two generations.
