Thanks for the reaction!
In terms of what's gonna happen after everyone's individual introductory eras are out (the HOK albums), I think I remember seeing somewhere that GF Ent (their company) is planning on initiating the next phase of their giant storyline/lore. What that is? I'm not sure.
As for touring, Kingdom is actually going to be going on their first American/North America tour later this year in around September! Here's some info on that if you're interested to see: (https://twitter.com/studio_pav/status/1662519038650482691?s=46&t=kmq999UotZa2Pz9sRzsyBA)
