The Wii is a good idea to experiment with, but I think the system is going to seriously flop hardcore, and I wouldn't be surprised if it costs Nintendo big time, maybe a repeat of the Sega downfall. I think it's fairly obvious that Sony will be the winner, unless Microsoft attempts to devour them like everything else. Let us also not forget that PS3 will be completely backwards-compatible, as where even though 360 will be, Microsoft cut their X-Box Live support to old users and forcing the upgrade.
As for what GhoS said, I'll bet you $50 U.S. dollars that PS3 beats Wii within the first year all 3 are on the market. And my email address is
[email protected] if you're on for that bet, and I use PayPal.
One more important thing to note, a name doesn't always count for much, but I seriously think Nintendo would've done a whole lot better if they kept the name "Nintendo Revolution."
