As long as Naughty Dog gives their all in the story mode, then an online would be a nice bonus, like MGS4 w/ MG Online. Never hurts to add more feature as long as they dont take out any.

Nope, Uncharted has a great single mode, that's more than enough.

Coop is the only kind of multiplayer that would be doable with Uncharted and still be good.

So no.

Probably wouldn't as it might ruin the game

Maybe if it were something like "find the relic" type thing, but how long could that remain fresh? As for deathmatch/etc., I say hell no! I just don't see how it would make sense in context with the established universe.

i think they should put some kind of online multiplayer, i think they could make maps that could be suited to it.

What about a Horde mode? Co-op campaign? Races (I hear Uncharted 2 has much more freedom over climbing and stuff, so, like climbing up a cliff the fastest, etc).

A juggernaught mode, like thekitchensink suggested, could also be fun.

Nooo!

only thing i can imagine working properly is some sort of "defend" something coop thing with various chars of the game.. like up to 4 people.. left for dead style in a place defending against a horde of enemys. .. But i don't want them to throw in multiplayer and neglect the singleplayer in any way.

 Single player co-op: the new fad?
