Was just about to post this. I'm going to assume like everyone else will and say one of them is Killer Instinct.
The other, who knows but I love the fact that we don't know. Considering Q1 ends in March I will guess they are going to announce the games at GDC. I know Lionhead is working on some games and Peter said we will probably see something there so that is my guess KI3 and a new Lionhead game.
