My theory (based on nothing) is that there will be an Orange Box 2, with EP3, Portal 2, and some updated form of Counterstrike.MarsProbe said:It is taking quite some time, but I'm willing to wait for quality. I wonder if they are solely concentrating on making episode 3 at this point. There is of course the Portal 2 theory, but it makes me wonder if they're also working on a new game engine.
As Valve don't seem like the kind of developer to just use the latest Unreal engine that most others seem to do.
