Personally I would love to see a nicer Universal store, not that I don't like the one now it's just too small. Second I wouldn't mind an exotic/novelty shop based off of IOA somewhere in City Walk...maybe an Ocean Traders Annex.
Not really a shop but I would love to also see a Bowling alley or hi-tech Universal themed Arcade come, the Nascar one on the second level just doesn't so that for me..Maybe an attraction like WonderWorks, Ripleys, or a haunted attraction...Hopefully Universal has the vision or plan to make City Walk a potential third day part of the resort, right now it's an end of day part which isn't bad, but it could be more.
Interesting....So much for my water park idea based off of Angry Birds, Temple Run and some other apps...
