We all knew it was coming, or not coming as it were. Valve’s highly anticipated Portal 2 was proudly flaunted at gaming expos throughout the year, and the company was even so brave as to publicly proclaim February 9th, 2011 as the day to mark on your calendar.

Well grab the white out, cut out the day, buy a new calendar, because February 9th, 2011 is officially just another day. The company has announced that the Portal 2 release has been pushed back until sometime around April 18th, 2011 (note the lack of a hard launch date).

A cheekily worded press notice reads

VALVE ANNOUNCES SHORTEST DELAY IN VALVE HISTORY

Valve today announced that Portal 2 — the sequel to the ground-breaking title that won over 30 game of the year awards, despite missing its original ship date — will now be available the week of April 18th, 2011. 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. Though this convergence spells doom for humanity, it will not affect the new Portal 2 release date.
