Hype is fine.
The problem for the PS3 fanboys is that the PS3 is in last place, both in total and weekly sales, and so whenever a hype worthy game shows up, they have to show that their console of choice is in fact not down in the dirt and that the console still has good exclusives coming out, which I think is the reason for why so many fanboys seems to get more excited about a good exclusive.
Of course, they are less prepared for any potential backlash, because as a group they have hyped each other up for a certain game, and wont willingly accept fault without trying to excuse it first.
Also, for me personally, the terms Halo Killer and "this game will help defeat the xbox!", are total rubbish. The PS3 is not doomed, does not need a Halo and does not need saving. It is in fact doing fine on its own merits.
I have reached a point where games like FFXIII doesn't matter to me at all (in sales, I never actually cared for the game as a gamer). I don't care if it surpasses the Xbox 360 in sales or not, that is not why I bought a PS3 and that is not why I still enjoy my PS3.
