It could easily be filled all day. From old WSOP episodes (2003,2004,2005 main event) to the circuit events this year to the Poker Superstars and WPT to poker shows and poker interviews from the WPT and WSOP as it airs live.

I would expect to see an announcement for it by mid 2006. Give it a little time after the splash that the airing of the 2005 Main Event will have.
