I'm pretty sure thats correct, i've heard that they don't like the Wii system and that they think it "can't handle" games like MW2.
OH HAI I HAS PITETION FOR COD LOLOLOLOLO!!11!!!!one11!
How many times do I have to say it? Petition never ****ing work. Ever.
It's not gonna happen, and it blows. I remember reading that of the alternating creative forces behind new COD titles, the one responsible for Modern Warfare isn't interested in developing for the Wii. We'll probably get the next installment of the series, but it'll be the same old WWII locations and weapons...
