You may not be able to buy copies of Call of Duty: Modern Warfare 3 just yet (well, not all of you), but you can always get yourself queued up for battle with the game's Elite application, which is already available for download via Xbox Live Marketplace. Coming in at just under 100MB, it ... uh ... doesn't do very much until you have a copy of MW3 and some multiplayer under your belt, as we were met with a prompt on load asking us to do as much before jumping into Elite.
The client has yet to arrive on the PlayStation 3's PSN, but we're betting it'll be available tomorrow at some point alongside the company's weekly content update. Unfortunately for PC users, Elite won't be available at launch tomorrow, but instead will arrive "when it's ready." And in case you haven't been paying attention, the game launches tomorrow on Xbox 360, PlayStation 3, and PC.
