Microsoft may of canned 1 VS 100 trapped on tape but for many people that they have abadndoned live episodic games on Xbox Live as of this time. Instead seems like they are creating a second go and they are now beta testing a fresh game show, Full House Poker, which features a method of Hold'em called Texas Heat.
Avatars will probably be used to represent players revealed and will have unique tell signs. There will be also new accessories to your 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 likely be saved between sessions. Full bola House Poker may also feature a leaderboard so that you can compare your card shark skills in your buddies.
I think it could be a great incentive should you could win MS Points or XBLA games as prizes for going to date in the tournament, but that is just me wishful thinking...
No word on when exactly Full House Poker is on its way out yet, but I would not be surprised to discover it out by next Summer.
