Not at all concerned about the theming - but am concerned it's another screen based (possible motion simulator) attraction.
It really dilutes other good screen attractions when you literally have motion simulator after motion simulator. In this area alone, you're going to have Shrek, Despicable Me, and Transformers, now this.
If anything i thought Twister was a very good attraction, albeit a little dated. They have an updated version of this in Singapore - which is a lot better than the Twister show in Orlando.
Don't universal have some link with NBC? It would explain the Tonight Show link.
Furthermore on the rite, if it's just a static screen and you sit there then that would be terrible. If it's something like Soarin' then we can actuall rejoice.
