I'm not arguing for or against Gen IV remakes, but wouldn't the presence of locations they otherwise could have saved for those remakes be a point against remakes? It's not like the Mega Latis where we knew they existed but they weren't officially available, serving as a nod to the coming Gen III remakes; these are actual locations they put in the game. It's like saying that the presence of Zygarde and the existence of the basement of Resolution Cave were a sign that we'd get a belated third Kalos game in Gen VII.
I'm not saying we are or aren't getting Gen IV remakes; I'm just wondering why this is a point in favor of them happening.
