MiceAge was not the only place to report on a coming Star Wars Land -- at least one other site reported it too. I always give MiceAge credit when they're right -- but the fact remains that they have been wrong a
lot over the years. It's not even their fault -- they hear bits of info that may be discussed or tossed around a Disney boardroom at one time, and then those plans change and become invalid. Disney changes plans a lot. Also, the inside 'leaks' dry up sooner or later too.
MiceAge apparently did not know anything about the reimagined Space Mountain, nor did they know about the new version of Star Tours -- never once did they mention those things. The whole "Season of the Force" concept slipped past them too. They can't win 'em all!

Those were all very surprising.
And where is the Marvel Land in DCA that MiceAge has been saying was going to happen? I was waiting for that news, but it might be announced at the 2017 Expo. I think it will happen -- or a version of it will happen -- down the road, but I really thought it would be sooner rather than later.
So, just as with any rumors from any source, sometimes they are right and sometimes they are not right. We always love discussing rumors here on the forum, from any source. It's fun to toss around rumors and speculate about them!
