If sony made the studio bigger and possibly split it this would be possible. I would be all for it keeping uncharted at high quality while giving the great creators of original ideas a chance to make another great series.

I would let the series age a little, maybe work on another title then unveil U4....I wouldn't mind if the third was the last, I love uncharted and I'd hate for it to become some milked franchise

They should feature a new main character for PS4. Maybe keep the title Uncharted: blah blah something something. And make the main character a sexy hot babe coz I'm a sex maniac.

its best Naughty just abandon the Uncharted series altogether, after the massive damage they have done on UC3. they should just scrap the whole thing.
hope their next IP wont be a failure like UC3

Uncharted is one of those franchises where you could could make twenty games if you wanted. Each one is a seperate adventure.
