I did some tooling around Google maps and compared buildings (F&F vs. our Earthquake and their Disaster building). There's no way they can cram it in there. While they could theoretically go into the backstage area for the main showbuilding, there are two things to consider: 1) It wouldn't be a tram animation. The vehicles would have to make a full circle back to the loading station. If they built it the same way as ours, they would have to add scenes to make it work (Which there isn't enough space for) or make the vehicles go backwards towards the station (Which isn't going to work capacity or story wise). 2) While they could readjust an Orlando version to go "full circle", there's one thing that's in the way: Hogwarts Express. I would imagine it would be very difficult to build a tunnel under that track just to go backstage.
The only reason this rumor got any fuel was because it was originally anticipated as a glorified KK 360 or another mere animation like how Disaster is. Now we're learning that it's a full-blown mega attraction integrated on the tour and there's just not enough space in the Disaster venue to justify it.
Looked at Hollywood street/T2 and there's still not enough space to put it there. Besides Disaster and T2/Hollywood, Kidzone is the only possible location they could put it. Unless plans change, they probably want to use that space for Bikini Bottom or something family-oriented. Unless they put it in Kidzone, I think F&F will be ours to claim. Again, anything could happen (Look at Transformers), but I just don't see them getting it. At least, it wouldn't be an exact clone of ours but without the tram.
EDIT TO ADD: I also just realized something: This is the best motivation for guests to keep their glasses throughout the tour. Now they won't be tossing them all over the backlot.
