Personally I don't think the console war includes the Wii, the console war is between PS3 and 360 only.
Ill tell you the reason why, the PS3 and 360 are next gen consoles and lets face it, the Wii isn't really next gen.
Nintendo made the Wii not with winning a console war in mind, they bought out a completely different type of console which is in a league of its own and can't really be compared between the other 2, its a completely different type of console.
This is what Nintendo wanted, this way because it isn't in the war all the PS3 and 360 owners will probably buy a Wii too(like me I own all 3).
