TDO is delaying the opening simply so they can have something new for 2014:
• 2012: BatB, TLM, CircusLand
• 2013: Princess Fairytale Hall (and a large influx of guests coming for the rest of the FLE)
• 2014: SWMT
In that same time, the new Potter expansion will probably be completed.
In no way do I see Avatar opening by 2015. I wouldn't be surprised to see TDO try and milk the FLE for years. If they can't even greenlight the MI coaster (when it falls perfectly in their timeline AND there's a new movie to promote), I have absolutely no faith we'll see anything else of substance any time soon.
That's fine. I sincerely wish to thank Disney and TDO for making to so easy for me to decide between WDW or Uni for our family annual passports come 2013. The SWMT isn't anything I, or my family, need to spend a thousand dollars to see, and (as annual passholders for the last 5 years) we've grown more and more tired of your theme parks with every visit.
We don't even expect E-tickets. Just some kind of new attraction at each park, each year to make them continuously fresh (ya'know, like every other park in the country does). And no, upgrading old and tired attractions (like Star Tours and Test Track) doesn't count!
Delaying the opening of the SWMT is a joke, and what makes it even worse is that it will make the entire FLE a construction zone for at least a year and a half more than it needs to be.
