Poor, poor Wii gamers. There's much to love about Nintendo's system, but when it comes to multi-console franchises, the Wii just falls short (with a few notable exceptions). The fabled Call of Duty: Modern Warfare is headed to the Wii this fall, and it will be quite different from its brothers on more powerful consoles. All is not lost, however; there will be co-op in Modern Warfare, which was lacking from the PS3 and Xbox 360 versions. Great news, right?
