Valve has confirmed that it is not developing any titles for portable or mobile systems. "We're about people sitting on their couches or at their desks," writer Chet Faliszek told Kotaku in a recent interview. The company has not looked into expanding its development beyond PC and consoles for future games. "We haven't forayed into [portable gaming]," Faliszek said. "It's just not a space our engine has been looked at or optimized for." "We're slow to move on to new platforms," added Igo Madal, project lead for Counter-Strike: GO. Valve is currently developing Dota 2, which will release exclusively on PC. A release date has not yet been announced.[/p] Source I like thier take on mobile gaming.
