Perfect Dark Zero didnt fail.
It's looks bloody amazing to me.
It's true, they're isnt any killer apps for the launch..but when has they're been?
PS2 had a lack lustre line up with its big games as Madden, SSX, Timesplitters and the game of all games, Dynasty Warriors ( Oh yea)
That's a pretty crappy lineup to me. Timesplitters 1, wasnt that great.
Gamecube had a crappy list too, with Wave Race:Blue Storm, and Luigi's Mansion. Rogue Squadron was pretty cool, but not nearly an killer app.
The PSP had a pretty crappy launch list too.
Same with the DS.
A failed launch doesnt really showcase how good the console will sell. The PS2 outsold XBOX, not because of its launch, but because of the time factor. It was out for an whole year before, and when the XBOX and GC came out, the PS2 was getting ready to release games like ICO, GTA 3 and other crazy good games.
It might happen this year with the PS3 launch, because they're good games coming out for the XBOX 360 later this year.
Lastly, whenever somebody says well, Sony will win again this generation because it won the past two generations. I tell them to think clearly because how did Sony take the mantle from Nintendo?
Nonbody has loyality to an console company anymore. (Aside from Die hard Nintendo fanatics)
