Steamfriends Site

Steamfriends site today received a teaser image from Valve appearing to show Gordon Freeman, protagonist of Valve’s Half-Life video game series, with an Apple logo on his chest. The image was accompanied with the following explanation: “In anticipation of an upcoming announcement from Valve.”

Valve has not offered any additional information on what we can expect from them or when more news might be available beyond “soon”.

MacNN received a different teaser image showing robotic characters from other Valve games mimicking Apple’s “Get a Mac” ads starring Justin Long and John Hodgman. The report suggests that we may see an announcement at next week’s Game Developers Conference in San Francisco. The image here represent turrets from Team Fortress 2 and Portal:
The presence of six dots along the bottom of the images, apparently for navigation reference, suggests that an additional four teaser images may have been sent to other outlets.

One more image has been posted at Rock, Paper, Shotgun, revealing that Steam is coming to Mac:
I guess it’s a matter of time now before we will hear the real word
