Uncharted 2 falters, no local co-op for Uncharted 2

[Vetteman94]

I dont see what the big deal is, for a game that wasnt even going to have any MP elements at all, now is leaving out a part of it. Wasnt the co-op parts supposed to be like Resistance 2, where it was a separate story/missions? If thats the case whats the problem?
