While I'm glad they changed the concept on this, I find it hard to get excited for this knowing that they haven't even started construction on this, so this will be five years away at least. On top of that, this will be the only major addition DLR will be getting post-M&MRR (Not counting Tiana as that's an overlay).
It sounds like they're going to make this an Indy or Rise-caliber dark ride, which I think is the right call. A big IP like Marvel/Avengers demands something a little more than a simulator ride. Plus, DCA needs that kind of dark ride to balance out the ride offerings. DL already has quite a few heavy-hitter dark rides. DCA needs at least one more I do think this will be very screen heavy though. At least just as much if not more than M&MRR. For those concerned about space, they can easily cheat the space like Rise and Transformers by having it go two stories. Boom Problem solved.
I have a theory that everything else that we were "supposed" to get like a TL refresh was eaten up by the budget for this. But I hope they break ground on this soon because this kind of ride should've opened with Avengers Campus. Imagine GE opening only to have to wait another 5 or 6 years for Rise. Just imagine we wait all of this time for this to be a copy of the Simpsons Ride. LOOOOOL
That being said, DCA needs a new highly themed family coaster. Badly.
