Haven't played this game in a while, any upcoming news?

Perhaps a new expansion or sequel even?

Well, there is an upcoming iPad and Android tablet version as well as the recently announced Frozen Endzone. The latter is kind of a sequel, but featuring a different scenario (american football variant). And if you're into semi-competitive gaming there is the monthly RPS (Rock Paper Shotgun) league.

pit_kling pretty much said the essential.

RPS season 19 on-going now
