What exactly guarantees a console will be a success at launch as well as overall?

 

according to professional sites like vgc or n4g it is the name "sony" whic guarantees a consoles' success. others are sometimes "allowed" to come close (because of a not-so-good start by sony, of course - others are always worse) but they will have to live with the obvious taunt of the elite race.
