And what of the Santa Fe? Is that not getting a retheme as well? Maybe one will be Star Wars and the other Marvel.. 
Well, they already re-themed it to Cars (shame shame shame

)... I can't think of another iconic part of the US, that hasn't been covered.
Except:
- New Orleans. Could work, but they would have to add some serious river work like in Orlando.
- Las Vegas. Will not happen. Because it's tacky. And useless without the strippers and gambling

- Hollywood. I agree it's more fitting around the studios.
- South Beach. Could work with all the neon (same as Santa Fé).
Really looking forward to see what they will build.
