Ufc Undisputed 2009 questions: demo release date?

First off i was wondering if anyone knows the demo release dates for ps3 or xbox. Also was wondering if anyone know if there will indeed be legends on the game. I read in december that Dana white confirmed legends and specifically mentioned royce gracie, and now the roster has came out and no legends, not even randy couture. I know they will have escudero and bader as dlc but do you think theyll have fighters such as couture, cote, carwin and any other fighters downloadable? Thanks
