While I hate to be gloomy, if the attraction DOES indeed feature guest interaction (gaming, as would make sense for WIR), I wonder how it will be implemented.
Guests love the shooter rides because everyone plays by themselves and against each other together in an easy-to-understand carnival game style atmosphere.
Guests seem to... dislike... MF:SR because it requires them to do more complex gaming while relying on others that might be better or worse than they are.
WIR seems to me an interesting vector that involve individual play, but perhaps something a little more complicated to understand. Unlike all the other examples, though, it's possible that people will essentially be playing alone, like the Magic Carpet experience in DisneyQuest.
Also, I wonder how much of this will be translated into the "Play!" Pavilion... I had thought WIR was going to be a huge part of that area, odd that they've decided to split the IP.
