Considering Springfield just got expanded, Forbidden Journey is Potter, Minions/Despicable Me is Universal's Child, DWT will be the newest thing, and Transformers...is an oddity.
I would imagine it still sells enough to stay as it is, and they need more than just one attraction in the LL when things hit the fan and Mummy/Panda/Restrooms/Studio Cafe closes (Not to mention the rumors of JP closing).
I would say Transformers is safe.

I'm going to drop a bomb, as I do intend on saying this, and have gotten permission to do so,
In the time-frame between D23 to now, they have made changes to the game-plan of Super Nintendo World, not just in Orlando, but also now for Osaka and Hollywood.
If they weren't having alterations, Kidzone would've been down by now and Osaka would've been further along than getting to work in Late January on footers.
Add Soundstage 22-25 to the mystery, and the changes that seem to be ongoing, and the rest can be said in one word: Re-Structuring.
I would love to be proven wrong by
@Chris, but that I have heard that SNW has changed, by multiple accounts.
And that one of the changes that I can confirm, is more that Donkey Kong is coming to Hollywood, in some shape.
