Battlefield 3 vs Modern Warfare 3: Which side are you on?

WithEA/Activision

With "Battlefield 3" launching Tuesday and "Modern Warfare 3" launching Nov. 8th — the lines have been drawn and so have the guns. So very many guns.

But which side will you join?

All of the video game industry has its eyes on this rivalry that pits Team DICE/Electronic Arts against Team Infinity Ward/Sledgehammer/Activision — a rivalry that has inspired passionate side-choosing among gamers around the world.

Of course, the big question is: Which game will come out on top in the long run? Game analyst Michael Pachter of Wedbush Morgan Securities thinks he knows. He told Forbes that he predicts "Modern Warfare 3" will dominate, selling some 16 million copies worldwide this year while "Battlefield 3" will sell half that at 8 million copies globally this year.

Interestingly, he also predicts that some 2 to 3 million gamers will buy both titles.

Of course, if Pachter's predictions are correct, the big winner here is going to be the video game industry. He believes the two games will generate more than $1.4 billion in revenue and make up 15 percent of total packaged videogame software sales in the fourth quarter alone.

Ultimately, both games will run you, the player, $60. And the real question is: Where will you spend your money and your time? The developers and publishers have released the launch trailers for each game. Check them out below and then cast your vote.
