What the hell could it possibly be? And just imagine the release date. Say Ep 3 comes out in Christmas 2009; Valve will have taken 5 years to make 15 hours of gameplay on an old engine to boot (incremental upgrades to Source or not, its old). I'm not really complaining about the game quality, since I love HL2 to death, but the waiting is interminable. Predicted release date for Half-Life 3: 2016
