I don't think they will release a new IP until next gen, 2 IPs is enough to be working on. May I point out last gen they only had 1 year between most of their titles, and the reason UDF took 2 years for only SP was they had to learn a new way of coding. This time they have put about 3 times as much content, and it already seems pretty complete. They have enough resources to release a game every year after Uncharted 2
