The game is currently in closed beta, but I signed up to be a beta tester and was already in before this post was finished. Also, yup, I did play a round right quick, and it was totally awesome. In so many words, it's You Don't Know Jack, but played asychronously against Facebook friends. Rounds are shorter, and there's some microtransaction stuff in there, but it's pretty much the same game you've been playing (and loving) for 20 years.
Regardless, it's free and seemingly unobtrusive in regards to your Facebook account, which sounds like a big winner to us.
