A collective groan was emitted from gamers earlier today when it was announced that Portal 2 will be delayed once again. Â Originally set to be a Fall 2010 title it has now moved into Spring 2011. Â It was delayed once until February 9th and today it was revealed that Portal 2 has now been pushed back until April 18th. Valve was quick to point out that this two month slip not only marks the shortest delay in Valve’s proud tradition of delays, it represents the approaching convergence of Valve Time and Real Time. Â Valve assured gamers that even though this convergence spells doom for humanity, it will not affect the new Portal 2 release date.
