Valve finally came out with it. An announcement we've all been waiting for.
Yep. Portal 2 has just been announced. Announced for Christmas this year, the game will be a sequel to the life-changing, medium-altering, genuinely funny original. I remain slightly skeptical, however, as it's hard to see how they can improve or even equal the ingenuity and general suprise of the original.
Then again, it is Valve.
