Sorry, I just think that sounds terribly boring for them to only have one art style for the rest of the series. I get the appeal of consistency and I might agree with you if we were talking about a brand-new, mainline entry, but KH has a lot of potential to explore different genres and styles now that the Xehanort saga is over. We have the Quadratum stuff exploring a more realistic style, so I’d be excited to see what they could do going in the opposite direction.
The KH3 style works well for the worlds based on CG movies, but after seeing the Hercules characters in UE4, I’m not as confident with the handling of 2D properties in that style, which most UX worlds are. But I’d even be down for a bit of a hybrid situation taking after DQXI’s ability to swap between 2D and 3D modes. Have Daybreak Town (and maybe Wreck-It Ralph) be fully explorable in the KH3 style, but when they use the Book of Prophecies to enter a Disney world, switch to a 2D classic style like going into a storybook or something. That’s just a rough concept for sure, but anything along those lines that does something different from what we’ve already seen in the series would be welcome.
