Microsoft may of canned 1 VS 100 trapped on tape but for many people that they have abandoned live episodic games on Xbox Live as of this time. Instead seems like they are passing on a second go and therefore are now beta testing a different game show, Full House Poker, which features a layout of Hold'em called Texas Heat.
Avatars will probably be used to represent players up for grabs and will have unique tell signs. There will be also new accessories for ones avatar to sport also. (Maybe a Full Tilt hat?)
Players play for experience points and chips in addition to their overall progress and bankroll are going to be saved between sessions. Full House Poker may also feature a leaderboard in order to compare your card shark skills for a buddies.
I think it will be a great incentive should you could website win MS Points or XBLA games as prizes for going up to now 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 may not be surprised to determine it out by next Summer.
