The GMR vehicles are being scrapped as is the current "trackless" floor. The only thing to remain in that building will be the surrounding walls.
Martin said just the other day that only 5-10% of the building will go unused and i'm inclined to believe him over Hill. I mean, Hill just got the scoop on the cut third Bantha ride. Mice Chat had that a year ago. A flipping YEAR!
Len hates when I bring it up, but when I questioned why we included him in the fact-based Unofficial Guide (I was fact checking a section and found a Hill blurb with nothing to support his crazy claim) the response was "Jim Hill provides color commentary for entertainment purposes and is not part of the factual portion of the Guide."
