Admittedly, not much of a preview. However...

 "It's an excuse for us to get a bunch of characters from the industry together and let them interact as themselves in kind of a 'behind the scenes', 'back room' environment," explains Sean Vanaman, writer and designer at Telltale Games. "It's a poker game, but it's a dialogue-centric, character interaction-based poker game."    

 "There's more speech among these four characters than the entire cast of a typical Sam & Max episode," explains Rodkin. "But all of the characters' creators have taken a pass at the script and signed off on things every step of the way."    

OH WAIT, FUCK FUCK FUCK FUCK 

 Telltale hopes to make such dynamics believable and entertaining, but also authentic: Strong Bad, the Heavy, and Max will all be voiced by their original actors, with Tycho's debut speaking role coming courtesy of Bay Area beatboxer, vocalist, and Telltale VA vet Andrew "Kid Beyond" Chaikin.

Waaah, I want my Thumbs back. 
 
Edit : Man, as much as the impression that the game is "Poker with wacky characters" is turning out to be true, I think I might actually get it now that I think about it. 
I'm still not thrilled about Tycho's voice.

Kaos is right Poker is best with 5-6 people. "
