The general public is going to love Guardians Breakout. They've been told they're supposed to. They also loved ToT, even though you'll hear fans here (mostly WDW) claim no one liked it and it was inferior to WDW's version, so who cares etc.Agreed. Also, the DCA version hasn't yet opened and they haven't gotten any feedback from the general public. (Not that they typically care.) And I would assume they would want to sort out any Marvel logistics before they go all in on the Guardians tower. They may not be able to do what they are doing in DCA at DHS in regards to a Marvel Land. I'm assuming the only reason why Guardians is happening in California is because of the coming expansion.
The thing is Tower was a classic. This attraction will never be. The GotG are not going to have that type of staying power (just watch until someone tells me how good the much lousier than the original Guardians 2 is doing at the box office as some sort of justification).
Guardians was the hook for the Marvel Land at DCA. There was always (as far back as the purchase became a thing) the idea that park would see something ... but when Chappie was able to pitch this to The Weatherman, and sell it, the whole Marvel Land sorta grew up around it. ... All having nothing to do with DCA's theme, but, again, that's fine with today's fans who are ignorant of the difference between theme parks and IP/franchise/BRAND parks.
But I do want to state again ... that Marvel plans for WDW have been (likely still are) rethought.
