Well ... considering all the other info on that page talks about the new ride storyline, etc -- and that the height restriction matches internal info I've seen on CM sites -- I'm going by that. Plus ... it's logical. Considering the popularity of JTA and all things Star Wars by kids -- plus Disney's recent push for "family friendly" options -- I can't see them redesigning a popular ride in such a way as to shut out a large part of the potential kid audience.
Where did you get the 44" rumor from? Could you link to that?
