Why do people keep claiming MGS4 is PS3's saviour?

Sorry superchunk but I have to agree with darth...I have seen a lot of posts but I am sure that I didn't read somewhere PS3 sales will double (maybe for one week though).

Still it would be strange it this will not sell well in NA and Europe (including Others) and move some systems....In Japan PS3 will see a nice boosts for some weeks and that is it..

 ok, obviously double is an exageration. However, there have been plenty of posts that this game will seal the deal in a major way. Many even that it will cause PS3 to pass 360 this year, which is directly against all trend analysis of the PS3's sales thus far.

In Japan it won't do much. MGS has sold the least in Japan every time. 

 Wooha XD.  Who said that?   *Hopes it is not me when I was drunk posting on VG*.
