According to Valve, this is no reason for anger:
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.”
Yes, Portal 2 has been delayed, from February 9th to April 20th in North America and Australia, and April 22nd in Europe.
The original press release said “the week of April 18th, 2011”, but according to Valve, certain retailers may release it on different days.
There’s not much else to say here, as the press release did not contain any other info. Apparently we’ll hear more closer to release.
And yes, it really sucks.
