ps3 modern warfare 2 to compete with 360 version?

[ps3-sales!]

I'll looked at all the next gen call of duty's since 4, and the ps3 looks to be catching up.

 

call of duty 4

360: 7.21m

ps3: 4.12m

sales difference - 3.09m

call of duty: World at War

360: 5.24m

ps3: 3.13m

sales difference - 2.11m

So hopefully for ps3 owners, modern warfare 2 will possibly follow this trend and only make a 1 million sales lead for the xbox 360. thoughts??
