I don't know, has this ever happened before? All top 3 software on the charts are PS3 this week.. well at least that's what I expect to happen.
1.) God of War 3 - 1.2 million
2.) Yakuza 4 - 350-400k
3.) Final Fantasy 13 - 250-350k
I remember the last time the PS3 topped the charts with more than one piece of software was around the same time last year, with the Killzone 2/Yakuza 3 release.
edit: sorry, i forgot about the exclusive thing. thanks. oh and forget about this thread. apparently pokemon is going to outsell god of war.. i forgot. nevermind :)
