Never happen with the 360 still in play. Not only would they have to rebalance all the tanks, they'd have to redo most of our maps. Even though we share basic themes and map names, console maps are typically very different. PC maps are larger and generally more complex.
Oh, and the bushes. Lots of foliage in the PC version. 360 can't handle what the current systems have, it'd start a house fire trying to run updated PC maps.
