He'll play through 2016.
I say this because I think he's going to keep playing as long as he can regularly make SF berths at the Slams. As long as he can maintain his top 4 ranking, that should not be a problem and with Nadal such a big question mark right now I think the odds of either Tsonga, Delpo or Berdych pushing him out of the top 4 are very slim. So he'll be making SFs through 2014, I think. Then let's say his level drops in 2015 (he'll be 33ish) and fails to make a SF berth. He'll then announce that 2016 will be his farewell year and he'll play one last time in the Olympics.
