This is Universal, Disney's chief competitor... if they need to make custom-built simulators for USH's DM then I think they can afford it.
From what I've heard, it's a direct clone with one difference: two theaters instead of one. No dance party, but that'll be made up by the minion play area slotted to be installed on the graveyard of the coke soak. I believe that Cyber Grill is slated to be shuttered as a possibility for the new upper lot employee cafeteria. (once Potter starts heavy construction they'll need a new one)
Not sure how it'll be themed but they're probably aiming for a November/December 2013 opening. A small project involving the old Wild West venue will debut for the summer, but the marketing for the park will still revolve mostly around Transformers. HHN and John Murdy himself is going to have to get very creative because most of the areas they usually use will be completely unusable by all of the construction/new things.
The next few years are going to be interesting for USH, specifically the upper lot. The lower lot, sans minor changes with the adjusting Transformers, will stay relatively the same.
