NO,
GTA4 >>>>>>>>>>> MGS4
When Sony lost the exclusivity of the games, when they lost the exclusive content too, THEN the Xbox60 starts to potentially finish 2nd in this generation.
before this, the Xbox360 had no chance to finish 2nd in the long run
Sony really need to match the future price drop of the Xbox360 : it will be very hard for them
If they succeed to not lose too many ground in this fight in NA, then ALL is possible
Maybe the BR victory will hep a little ...
I also hope that Ninty will boost the Wii's stock to counter the Xbox360 arcade better than previously in NA.
Time to Work !
