Microsoft may of canned 1 VS 100 recording but i am not saying that they have abadndoned live episodic games on Xbox Live at this time. Instead it seems they are creating a second go and so are now beta testing a brand new game show, Full House Poker, which features a topic of Hold'em called Texas Heat.
Avatars will probably be used to represent players available and will have unique tell signs. There will be new accessories for the avatar to sport at the same time. (Maybe a Full Tilt hat?)
Players play for experience points and chips and overall progress and bankroll are going to be saved between sessions. Full House Poker can even feature a leaderboard in order to compare your card shark skills on your buddies.
I think it will be a great incentive in case you read more could win MS Points or XBLA games as prizes for going to date in the tournament, that is just me wishful thinking...
No word on when exactly Full House Poker is arriving out yet, but I may not be surprised to determine it out by next Summer.
