Tesco has put the listings back up (with the box art for Xbox 360) and have put out what seems to be the official description of the game:
This pretty much confirms we wont be getting “MW4” this time around. There’s still tons of questions as far as what direction Infinity Ward will be taking it in. One thing is for sure, we can’t wait for this coming week when all should be revealed… hopefully…
UPDATE: Looks like Tesco took down the listing again.
