Apparently, Uni has acquired the theme park rights to DC Comic characters (such as Superman and Batman) through an agreement inked with Legendary Entertainment. I believe this agreement extends the DC character rights to Uni theme parks, in addition to the one already in place with Six flags (acquired through Time Warner).
This, of course, does not invalidate their Marvel rights, but it clearly gives them backup in case they ever decide to give those rights up. If they ever do forgo the Marvel rights, Disney would, by default, gain the theme patk rights for those characters east of Mississippi, including WDW.
