From Micechat, re DL SW Land...
"...the actual construction phase of Star Wars Land will begin, and that program has been code named “Atlantis” by WDI. (Greek scholars will appreciate the Imagineers coded references here.)
When the construction phase of Atlantis begins later in 2016, the biggest warehouse, or “show building” in Disneyspeak, will be found in the northwest corner of the new land and will eventually block the views of Mickey & Friends. That building will be the home to the Stormtrooper chase and escape ride, code named “Alcatraz” at WDI, that
will feature autonomous trackless vehicles and nearly every other techno marvel WDI can throw at it.(emphasis added) The second largest building will be on the northern perimeter and will contain the Millennium Falcon flight attraction, which is code named “Big Bird”. These massive show buildings should begin to be framed in by early 2017, with a projected opening date that’s now pegged for Spring, 2019."
I like the bolded, italicized line.
Also, does anyone know if the rumored DL spring 2019 opening is the expected date for WDW? Can we assume that they will aim to open them at the same time, or is that not part of the plan (as was the case with TSMM and Little Mermaid attractions at DCA and MK)
