Alrighty guys time to let you know from a Tomorrowland Cast Member's perspective as I am. Space Mountain will NOT have walls be put around it at any time...what you see now is what you get. TTA does have a wall around it and to those who have asked it is going down, yes, so that you cannot see into the Space Mountain Complex but also because it is getting a little refurb itself...which includes: new up and down ramps, new turntable, new track lighting and new control consoles...as a part from Space Mountain and what I do know is happening there I cannot tell...but I can tell you what is NOT happening: NO new track layout, NO music, NO arcade refurb.
