According to a report on Apple Insider, Apple CEO Tim Cook paid a visit to Valve headquarters today in Washington, and suggests he and the firm’s Gabe Newell could be cooking something up. These leads many to speculate numerous reasons for such a visit and what the duo could be discussing, such as the “input, output, and platform hardware” Valve is currently hiring for, maybe even the possibility of Steam integration with AppleTV. Then again, it could have just been a friendly visit. Put your speculation hats on and start guessing. Thanks, Kotaku.
