Now you're talking. Potter, Marvel and Nintendo would be a great triple threat.
That is we're talking about a hypothetical situation. If Universals did acquire Marvel back in 2009, they might bring back Marvel-related stuff to USH due to the MCU success and possible might erect some of the stuff back stuff for a Marvel-related attraction at the Lower Lot. In this one, SNW might probably not happen. Due to the success of MCU, I don't think Universal might be inclined to bring Nintendo into its Orlando parks (however, I believe Universal might, considering how popular Nintendo really is, but I don't know about that one). However, because Universal move HHN back to Florida due to more houses, Island Under Siege-like scarezone may never happen again. Disney treats MCU the best they can be, however, they're still being accused of not wanting to put out R-rated movie because of their primary audience for decades (that is though if they never bought 20th Century Fox). Universal owning Marvel would eliminate some of these concerns and might bring MCU into a bit more mature and violent level even though most of them would be PG-13.
