The combined marketing push of the Tribute Store, Parade, Lagoon Show, and all of the merch surrounding it is giving me hope that this could be a pretty big thing.
The Universal Twitter Shark Tank parody and Unboxing video posted in the Tribute Store thread also seemed to imply that Dreamworks Land is being folded into this Nostalgic Summer push as well. Definitely seems like they're trying to make all of these tinier USF additions sum up to feel much more substantial than they might as a dozen seperate announcements.
