Microsoft may of canned 1 VS 100 a few months ago but for many people that they have abadndoned live episodic games on Xbox Live at this time. Instead it seems they are doing it a second go and so are now beta testing a whole new game show, Full House Poker, which features a topic of Hold'em called Texas Heat.
Avatars is going to be used to represent players available and will have unique tell signs. There will be new accessories for ones avatar to sport likewise. (Maybe a Full Tilt hat?)
Players play for experience points and chips in addition to their overall progress and bankroll will probably be saved between sessions. Full House Poker may also feature a leaderboard so you're able to compare your card shark skills for your buddies.
I think it will be a great incentive in the event 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 here is originating out yet, but I would not be surprised to find out it out by next Summer.
