Valve has announced that they are delaying the launch of Portal 2 to next year. The game was expected to arrive later this year.

The company said that they have no choice but to delay the launch. The idea is to make the game even better than they had originally planned.

Portal has been a major success for the company. The sequel would be launched on Windows Xbox 360 and Sony PlayStation 3.

The company has however still promised a surprise for their fans that would be revealed this month.
