[citation][nom]restatement3dofted[/nom]Half Life 3 doesn't even have its own entry on Wikipedia yet, heh. Considering there still isn't even a release date for HL2: E3, I wouldn't hold your breath for HL3 screenshots.[/citation]
There has started to be rumours that there won't be a HL2: Ep 3, just a HL3. With how freaking long they've been working on it (or ignoring it and making more L4D games) I hope that's the case.
I bet Valve is waiting to release HL3 until 3D becomes more widely adopted, and it will use it in some amazing or new way. It would make sense, since Valve is waiting an abnormally long time, when they easily could have made the game, and the HL3 or EP3 thing both have 3's in them, like 3D.
I wouldn't mind starting on it right now - and I'm going to bed in a few minutes!
Maybe valve need to hire a few more people. They can't be short of money, but the wait time of games (l4d the exception) shouldn't be so long on an engine that's already built (with some improvements on each release). Maybe they're proud of their 'Valve time'?!
