After Garo leaves this time around, it is likely not to return. And if it does, it will be after a few years like it did this time around...and only if there is a very large number of requests for it.

Yo-Kai I can see returning before Dawntrail, but I also wouldn't be overly surprised if it didn't come back.

Having to justify the costs for acquiring the permissions to use other company IPs can be a daunting task depending on which higher up in both your company and the IPs company you have to talk to.
