Possibly the same reason Episode 3's taking so long? I think you're onto something here.FinalHeart95 said:They're waiting until Portal 3 so they can call it "Portal 3D".
Marketing genius.
Anyway, I wouldn't really mind if they left Portal as it is, in all its 2D goodness. Heck, I didn't even know the PS3 would support 3D games.
Insta-kill energy balls flying out the screen towards me would do nothing but wreck my nerves.
