Jak 4 by the end of next year, will be next on the agenda, but then i see Uncharted 3 the following year. I've read that they now have multiple teams working at the same time thus reducing the time between releases.
[Edit] I must also add the fact that whilst it is not being made by Naughty Dog, Jak and Daxter: The Lost Frontier for PS2/PSP does release just weeks after Uncharted 2. Maybe this (if it is a success) might mean that Naughty Dog hands the franchise over (Keeping in mind the last two J&D related games would be made by other devs) [/edit]
