After speculation this week, Valve has officially come out to say that Portal 2 is indeed dropping this holiday season.
UPDATE: New details on the gameplay of Portal 2 have emerged. The sequel introduces two new characters and a previously unseen area of Aperture Science Labs. You will once again work with GlaDOS, but Portal 2 will have a two player co-op campaign with its own story that will force the players to solve puzzles together. Portal 2 will be released on PC and Xbox 360.
A brief press release from Valve stated the accolades of the company and the many awards (70) that the first Portal received. The sequel is currently slated to come out "this holiday season" but there were no details provided on the setting, plot or anything, really. Going to the Steam website to view the release though, I noticed that certain characters were underlined. This may be a clue for the continuing ARG which was hinted at earlier this week.
Here follows the complete text from the Steam website including the underlined characters:
Valve, creators of best-selling game franchises (such as Left 4 Dead, Counter-Strike and Half-Life) and leading technologies (such as Steam and Source), today announced Portal 2 for shipment this coming holiday season.
Portal 2 is the sequel to 2007's Portal, which won 70 industry achievement awards.

So the underlined characters are: D R A T M A N N H 0 N E E.
I have no idea what that means, or if it means anything at all. That's your job to figure out. Get to it.
