I think either xbox or nintendo is going to make the next system. Not for a couple of years though, at least like 5 or something. definetly not playstation though.
I'm hoping against hope that Sega comes back to it's former glory...I doubt it though.Nintendo will probably jump the gun and make a new system first,because the current Wii has low specifications,which will eventually dissuade potential buyers in favor of X360/PS3
