Leamax

This is the first we're seeing it and it's for an official update which happened yesterday...doesn't seem datamined to me?

It wasn't for an official update. If it was, then it would have been announced two days ago on KHUX Japan. 

I hate that her full outfit was data mined rather than revealed by Square Enix. Her outfit wasn't suppose to be shown until E3

Half of the KH universe will disappear with a snap

I doubt for a WiR world in KHUx most likely due to licensing issues with video game cameos.

Why do we need cameos? All they need is a Sugar Rush level, which could fit KHUX

Though I think he did say it would appear in a trailer, and this is a demo. But that would be great either way.

 

A little sad that this (might) mean Wreck it Ralph might not get a full world but this is pretty great either way. I think it would have worked really well to. But I do like that links/summons are not only characters you have met before because it's a good way to include characters that don't have a world. I guess Sora is just that good that he makes connections to people he has not met yet. 

This could mean that Wreck it Ralph will be the new world in Union Cross.
