Seems it is animated in Unreal engine:

Kind of interesting. I like the potential of Disney franchises that don't interact having a little crossover... I'm hoping they'll have someone to reign in the plot and make it more manageable. I like the KH story and its weird convoluted charm, but I don't think it would work for an actual series.

Maybe I'll actually understand the story. I quit the series after the first game.

That means the CG assets can be directly exported using Unreal Engine 5 to PS5 LOL, and Kingdom Hearts 4 is ready.

This has me excited if true :o

Can someone with more technical knowledge than me explain why a pilot should be made with unreal engine? Based on experience, I'd guess that the tools Disney has at their disposal are far more powerful. Maybe it was just quicker for a test of concept since Square would be more familiar with that, but I feel like using the tools that they typically use for CGI movies would be far better for an actual series.

Well, it seems that Square will actually be developing the show themselves, rather than Disney. So maybe Square is planning on sharing assets between the show and the next gen KH4 project they seem to be working on? 

This is really exciting. I haven’t actually used my Disney+ for anything yet so it’s nice to know I’ll be able to watch one of my favorite game series being adapted into a show on it.

Maybe, but I just don't know enough about game development vs show development to know if that would be efficient.  Seems like it would make the show harder to develop and lower quality, but again, that's just my lay opinion.
