Everyone is in termoil with what is going to be brought to Tomorowland. Based on rumors and fact I am going to supply a basic overview:
Obviously in 2007 the subs will return! During December of 2006, the Autopia shop will be moved to the location of hatmosphere ant the hatmosphere will be moved to the spot previously occupied by Radio Disney and Club Buzz will be returned to the Tomorowland Terrance. Later, the Peoplemover will return.
Hope that helps!
