Not very high. I would be a ENORMOUS drop off in quality, especially considering the fact that there isn't a second nub.

replace PSP with PSP2 and there might be a chance

It will happen I guess, Uncharted 2 was accidentally shown on the PSP remember Valkyria Chronicles? It was also shown on PSP then Boom Valkyria Chronicles 2 on the PSP.

it would most likely be the only Uncharted game i'd own.

No thanks.

I hope not, it will just be a disappointment in sales and in quality.

We'll only see Jak on PSP methinks.

i'd like to see demon's souls on psp
thats a game that actually fit the PSP.

70% chance

God Of War, Twisted Metal, Ratchet & Clank, Jak & Daxter, Little Big Planet, Ape Escape, EchoChrome, Everybody's Golf, Buzz!, MediEvil, Motorstorm, Syphon Filter, SOCOM, JetMoto, Killzone, MLB: The Show, NBA, WipeOut, Flow, Resistance, Gran Turismo, ATV Offroad, etc etc...

I'd say there is a pretty good chance we will see an Uncharted on the PSP(2) eventually.

I think it would be a good idea and could probably be a good game. I dont know what the fuss is about a "drop off" in quality. Its a different system whats the big deal? If you wont play because of a "drop off" in quality then I take it you don't play any of the highest rated games on the PSP because most of them are spin offs from console titles so they would all have "drop offs." The same can be said for many popular DS games. That's like people not watching their TV's because of the drop off quality compared to the Movie Theatres.

Also Naughty Dog doesn't have to do the PSP game. Infact most Sony titles for the PSP are not done by the console developers.
