Portal 2 is coming?

Yes it is,no doubt about the that.After succes of portal,there is no suprise that part 2 is coming.Actually the game develepors are saying that portal was nothing else but an test game.So we should expect an double plesaure with portal 2.Also u will be in an lab at the beggining of the game,and some crazy doctor will put many traps as possible to make your way to exit harder and harder.Im personaly expecting an good game from this.Big hopes for this!
