My hope, as well as some others who actually have some say in the matter, is that the new Space Mtn. at Disneyland will be a huge hit.
If it is, chances drastically improve that WDW's horrible, terrible, embarassing, sorry excuse for a Mountain can receive a makeover of it's own.
At Disneyland, the official line is November of next year.
For me, that is hard to believe. As of a couple of weeks ago, most of the track was in the mountain, with total installation of the track expected no later than early Sept.
I just don't see how they are going to need 13 months to test/adjust the ride system and effects. Unless....it is ready on 7/17, but they sit on it as incentive to lure guests back during the fall.
