Portal 2 Development Finished

Valve cofounder, Gabe Newell, has told a group of U.S. marketing students that Portal 2 development has been finished.

"We just finished Portal 2," he said. "It's pretty much put to bed and we're just waiting for final approvals and to get the discs manufactured."

Newell also confirmed that Valve's next game would be Defense of the Ancients (Dota) which would be released later this year.

Portal 2 is scheduled for release on PC, PlayStation 3 and Xbox 360 in April 2011.
