It's not a failure for them, they have made bucketloads of cash, but it's a failure for most other people. PC gamers have crappy multiplayer and viruses, one million modded xbox users got banned from XBL [and had their consoles vandalized] pre-emptively because of the impending release, associated content reports that Xbox sales are down because parents have been scared by reports of the ban, and a million modded xboxes that still play pirate singleplayer games are about to get dumped onto ebay for cheap. So we got screwed, a good chunk of the xbox crowd got screwed, and MS got screwed, but IW are laughing.
