We'd love to outright confirm that "OMG, yes, Steam is finally coming to Mac!" but that'd be a lie. Truth is, of the five images that Valve sent out to a handful of outlets (as seen in our gallery below) – each one depicting characters from separate Valve games in some form of faux Mac advertisement (from Half-Life to Left 4 Dead and everything in between) – none provide ironclad confirmation of our suspicion that the developer is likely porting Steam over to OS X.

That said, given the presence of six dots at the bottom of each of the five images we've seen so far, suggesting an iTunes-like image gallery with six images, we're hoping for an actual news release in the not-too-distant future ... possibly via that sixth image. For now, we've put in a call to Valve and will be speculating wildly in the meantime. Check out the five screens so far in the gallery below and get to the speculating with us, won't you?

Update: Valve kindly sent over the last image, which unfortunately doesn't "OMG confirmed!" our guesses. It is, however, the coolest (fake) ad yet.
