The last we heard of Kim Swift, one of Portal's chief architects, she had migrated from Valve to Airtight Games to work on some super secret project. But that was two years ago, so what's been going on since? Well, we're all going to find out later this weekend.

Not much is known at the moment, but according to the press release that Square Enix distributed to all press people this morning, it's an "incredibly fascinating and quirky game". One that Swift, along with the rest of her team, will discuss at PAX.

It goes down this Saturday at 7:00pm, in the Pegasus Room, for those attending. It's highly suggested to get in line early because A. many will no doubt be equally interested, and B. those panels rooms are generally way too small.
