It's been nearly four months since GlaDOS toyed with our emotions in test chamber after test chamber in the critically acclaimed, and commercial smash-hit, Portal 2.

Now, the malicious AI, or rather the actress (Ellen McLain) who voices the fan-favorite Genetic Lifeform and Disk Operating System, was outed on the Twitter-verse by her husband, announcing that McLain will be voicing a character in Valve's "New Game" - for science of course, you monster.

The notorious tweet from John Lowrie (the voice of Team Fortress 2's Sniper) has yet to be retracted, or flushed down an Aperture Science vacuum tube, indicating that maybe even the mighty GLaDOS can't erase everything on the Internet:

Ellen is going in Tuesday for a new game and more Portal work

While the mere mention of "more Portal work" certainly gets the heart pumping, we already knew that Portal would be receiving additional test chamber DLC - to tide players over until Valve's next title arrives.

It's no surprise that Valve is hard at work on a "new game," they're probably hard at work on a few "new games" - however, in connection with McLain, the possibilities become especially enticing. Aside from GLaDOS, McLain's voice can also be found in Team Fortress 2 and, certainly more intriguing, as Overwatch in the Half-Life 2 series. Could McLain be reprising her Half-Life 2 role for Half-Life 2: Episode 3 (though further episodes have been routinely debunked) or even Half-Life 3 (which is still in the cards)?

It's also possible that McLain is simply doing voice work for Valve's "next game" Defense of the Ancients 2 - which is set for a Fall or Holiday release. The timeframe would certainly fit, as production on the title should be wrapping-up soon - so discs can be stamped ahead of a Q3/Q4 2011 release. However, it's unclear why Lowrie would have been so ambiguous about the "new game" - if it was already out in the open.

There's always the chance that, given the success of McLain's work as GLaDOS, maybe Valve writer Erik Wolpaw is putting together a fresh role for the performer in a "new game" - which, for all we know at this point, could be an entirely new IP.
