Disney have confirmed that the upcoming refurbishment to Magic Kingdom's Tomorrowland Transit Authority PeopleMover has been postponed.
The refurbishment was due to start next week, however this has been canceled. It's been widely speculated that the refurbishment will now take place later in the year, at the same time as a major refurbishment in Tomorrowland, heavily focused on the Astro Orbiter. Tomorrowland hasn't seen any major change or refurbishment in years. With Fantasyland nearing completion, Disney are likely looking at ways to improve the Tomorrowland area.
