Microsoft may of canned 1 VS 100 captured but that does not mean that they have abadndoned live episodic games on Xbox Live as of this time. Instead it appears to be they are passing it on a second go and therefore are now beta testing a brand new game show, Full House Poker, which features a mode of Hold'em called Texas Heat.
Avatars will likely be used to represent players revealed and will have unique tell signs. There will be also new accessories for the avatar to sport also. (Maybe a Full Tilt hat?)
Players play for experience points and chips along with their overall progress and 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 for your buddies.
I think it poker rules showdown might be a great incentive in the event you could win MS Points or XBLA games as prizes for going up to now in the tournament, that is just me wishful thinking...
No word on when exactly Full House Poker is on its way out yet, but I may not be surprised to view it out by next Summer.
