Doug Lombardi from Valve has announced that Portal 2 is on its way at the end of the 2010. What’s even more interesting is that he has confirmed that the PC and 360 platforms will get the game but has not spoken of the PS3. It is well known that Valve has issues with developing games for the Sony platform and co founder Gabe Newell is not the biggest PS3 fan it’s been reported.

Speculation online has been also rife about whether that means an Orange Box 2, the original Orange Box came with Half Life 2 Episode 2, Team Fortress2 and Portal. Even on it’s own Portal 2 will do well but if it was bundled with Half life 2 Episode 3 then potentially Valve is looking at a enormous hit.

Portal 2 is set to include a CO-OP mode and is rumoured to return the player to Aperture Science Labs. New surprising characters are also expected to appear in the game with new areas to explore at Aperture.

Just imagine how complex the puzzles will be with a CO-OP mode using two player it promises much, including another cake maybe. The cake is a lie…is a lie but GLaDOS is back
