As I understand the refurbs are just step one. In between the programm also contains a step 2; WDS. This woua Toy Story Mania, a new (Pixar)show instead of Animagique, a quick counter restaurant instead of Toon Town photoppoint, a Hollywood street with shops and restaurants (including Starbucks), renewed Studio Tram Tour with renewed scenes, a Marvel land instead of backlot (RnRC>Spider-Man, Armageddon replaced by an Iron Man ride, Moteurs>Captain America). And finally a new Avengers ride for WDS 25th. Is that all? No, Wolber has a goal. A very nicr one. Getting a new ride for Adventureland.
Off course they want a Star Wars land, but it proposiled to be a mini-land. According to D&M it would contain Star Tours 2.0, Jedi Academy at Starport, a gigantic shop at the current Discoveryland theatre, a meet and greet at the Star Traders spot, a Millennium Falcon Walk Through and a Cantina restaurant. All placed from Videopolis to the current Pizza Planet. When? Who knows. Star Tours is for sure and the shedules are full with plans. But with new movies coming up and the new Star Wars lands they might bring the plans up front of the current masterplan.
I think the first want to focus on polishing the Disneyland Parc for the 25th, and want to leep the plans for afterwards. But whether the announce it or not on a next D23, it says nothing about what is happening. Do not forget they barely mentioned Ratatouille, Dreams or Jedi Academy. Disneyland Paris never announced anything big in advance. Every fan knew Ratatouille came way before Disneyland Paris formally send out a press release.
