It appears that we were right - Battlefield 1943: Pacific is in fact a downloadable game for the Xbox Live Arcade, PlayStation Network and PC.

Using the same Frostbite™ engine, Battlefield 1943 takes players back to WWII. The game offers endless hours of 24 player multiplayer action over three classic and tropic locations; Wake Island, Guadalcanal and Iwo Jima. Delivering the award-winning through-the-gun and vehicle warfare online experience DICE is best recognized for, Battlefield 1943 will have players battling in ruthless aerial dog fights and intense trench combat. Players can see the game in action at New York Comic Con (Booth #1441) from February 6th-8th.

The official trailer can be viewed above. This will be an interesting year for the Xbox Live Arcade and PlayStation Network - a lot of games have included multiplayer, but with the week-to-week movement of players their lasting power tends to only last for so long until its dead - and the ranked / player matchmaking systems certainly don't help the situation.

With XBLA getting Battlefield 1943 and CellFactor, and PSN getting both of those and Punisher: War Zone on top of that, it will be incredibly interesting to see how everything weighs in. I hope the 24 player multiplayer is server based too.
