Valve Teases Upcoming Mac Announcement, Not So Subtly [Apple]

http://cache.gawkerassets.com/assets...0x_igordon.jpgIs Valve finally ready to make the switch and support Mac OS X? A recent update to Steam hinted at it, now it's time for the Half-Life, Left 4 Dead and Team Fortress developer to be more blunt about it.
The developer has released a series of images "in anticipation of an upcoming announcement from Valve," giving some of its most recognizable franchises the Apple treatment. That includes Gordon Freeman from Half-Life in an iMac colored HEV suit (complete with obscured Apple logo), Team Fortress 2's Heavy in iPod ad form, a pair of turrets from TF2 and Portal doing the "I'm a PC" thing and Left 4 Dead's Francis expressing how much he hates "different."
Is this simply heralding the seemingly inevitable Steam for Mac announcement? Or will Valve go further, adding actual Mac OS X support for some of its Source engine games? As a Mac owner, I'll take just about anything.
Valve's also been teasing something Portal related lately. With company founder Gabe Newell making an appearance at GDC next week, could that "upcoming announcement" be right around the corner?
Take a peek at four of the released teasers in the gallery below.
