I'm honestly super curious about Tabata's new IP. He's probably been working on that with a small core team for a bit of this year, too (after his holidays, he's not in charge of the DLCs in such a grand manner where he couldn't do other stuff). It also seems that he's had this idea for a while now (probably even before taking on XV?), so it's exciting.
Can't say I inconditionally loved any of his games: XV was good, but dissapointing -for reasons he's to take the blame for and others derived from the schedule and game's history-, Type-0 was nice enough from what I played, but didn't grab me at all, and CC (never played T3B) was quite entertaining, but a game that muddles the whole FF VII universe to me.
So I hope his creative team is solid, because, while some of his games' ideas are great, their execution leaves a lot to be desired. I'll go and say that I actually expect XV's overall combat system to be present in this game, as Tabata seems to be the creator of that patent along with another guy I can't remember right now. Tweak it so that it's considerably newer (and doesn't depend on XV's exclusive abilities, like warping) and there you have it.
A fully fantastical AAA JRPG, with a darker tone and aesthetic (hopefully not the tired middle-ages) is something I could really use and that S-E could really benefit from, as it'd be different from the very manga-ish aesthetic of DQ, the cartoonish one in KH and the... weird things modern FFs usually do. Especially if it had a more classic-inspired art design, like:
