Continually people overestimate what impact PS3 software will have on long term sales. MGS4 may create some boost, but as the poster child of the PS3 since E32005 certainly a great deal of people purchased the PS3 already that will be purchasing MGS4.
Every month that goes by diminishes the impact that GT5 and FFXIII have on PS3 sales. More and more of the people that have to have a PS3 for GT5 and/or FFXIII will already have a PS3 when they arrive. How many of the GT5:Prologue purchasers will simply be treating GT5 as an upgrade? Meaning they wont purchase a new PS3 to play the finished version. Would Halo 3 had as much of an impact on hardware sales had it been released with 20 million XBOX 360 already sold to consumers? Sure the software sales would still have been great, but the hardware impact diminished. By the time GT5 and FFXIII hit the streets the PS3 will be approaching 20 million consoles sold. The impact will certainly be diminished (Especially GT5).
Its libraries that sell systems not a single game.
