MW3 vs. BF3

The two big contenders are going to duke it out at the end of the year. Which one will come out on top? There has been some speculation that BF3 will crush MW3, but the record sales of MW2 says otherwise. Even though Activision may have lost some fans due to its mishap with MW2's Javelin martydom, infinite noob tubing, hackers, and the nuke boosters, chances are MW3's record sales will double or may even triple that of it's predecessor.
