Microsoft may of canned 1 VS 100 captured but for many people that they have abadndoned live episodic games on Xbox Live at this time. Instead seems like they are doing it a second go and are also now beta testing a fresh game show, Full House Poker, which features a method of Hold'em called Texas Heat.
Avatars are going to be used to represent players available and will have unique tell signs. There will be new accessories for ones avatar to sport too. (Maybe a Full Tilt hat?)
Players play for experience points and chips in addition to their overall progress and poker rules raise after all in bankroll are going to be saved between sessions. Full House Poker will even feature a leaderboard so that you can compare your card shark skills in your buddies.
I think it will be a great incentive should you could win MS Points or XBLA games as prizes for going thus far in the tournament, that is just me wishful thinking...
No word on when exactly Full House Poker is originating out yet, but I couldn't survive surprised to view it out by next Summer.
