Sadly however..."Bet your way to fame as you compete against your friends and thousands of other players around the world in live Texas Heat poker game shows..." The concept sounds extremely like 1 vs. 100 with a coating of poker paint, allowing players to pick up XP and other rewards (including "unique tells and avatar accessories") by playing poker in "regularly scheduled episodes."
"...and that it requires an Xbox Live Gold subscription in the US, Canada, or Mexico."

It seems as though Microsoft are giving it another shot with the style of games. Poker isn't a bad choice I'd say... shame I can't play it.
