As if the news of Steam coming to Macs weren’t enough, fanboys can rejoice today for more great news from Valve. As the latest issue of Game Informer confirms, Portal 2 is coming and it’s coming to Macs.

The PAL Game Network has scans of the cover story from Game Informer, which shows the basic info about the game – developer, release window, platforms, etc. There isn’t much more information, other than the fact that the game will be incredible. If you haven’t played the original Portal just go buy the Orange Box. It’s easily one of the most enjoyable games I’ve ever played, no lie (the cake on the other hand…). And it all started as a trial.

Luckily for us, Portal 2 will be a full-length game, set to release this fall.

Portal caught an update on Steam earlier this week, giving the game an extended ending and teasing some details from the previously announced sequel. Well, it wasn’t officially announced but it was definitely confirmed.

Hidden in the update were all sorts of little clues, the type that keep forum rats busy slaving over cryptic messages to find ASCII art. A lot of the “clues” were actually little jokes from the series, but some of the messages led to ASCII images and several messages from the founder of Aperture, Cave Johnson.

The Steam forums are burning the midnight oil to figure out the meaning behind the messages. I’ll give you a hint, guys – Valve will tell us more soon. Until then you’re going to be looking at a bunch of ambiguous clues pretending you can make sense of them.

I can’t say whether or not this video is real, or whether or not that’s actually Valve’s Portal you see running, or pretty much anything about this video other than, “Please, suh, I’d like some moah.” The port could be real, particularly considering how terrible the controls look, though I can’t always match what his fingers are doing to what’s happening on screen. At any rate, take a look and dream a little.

And when you’re done, go grab some cake. I hear it’s delicious.
