I predict their release schedule to be something like this...
"Uncharted Team" - Holiday 2014 Release -> Uncharted 4 (Maybe something to do with Atlantis)
It would be logical to release another Uncharted in the series. It would be a perfect system seller for the Playstation 4 since it would be a part of an established franchise. They would have already announced their completion of the series if they were done with it I believe.
"TLOU Team" - Summer 2015 Release -> New IP or TLOU 2 (Maybe
Savage Starlight or space related game)
Their second release on the PS4 would be the perfect time to release a new IP if they were going to do so, and establish a new line of franchise games for the 8th gen consoles. Or they could create a sequel to their highly acclaimed and successful game The Last of Us which has generated a ton of buzz since its release.
"Uncharted Team" - 2016 -> New IP
"TLOU Team" - 2017 -> Sequel to first new IP or TLOU 2
