Certainly looks interesting.
Cygames have been almost solely a Mobile games developer although they've dipped their toes into the console and PC space in the past few years. 1 game on VITA and Steam. 1 game on PS4 and Steam. 1 game PSVR (JP only). 1 Steam game that was a mobile port. And about a bajillion mobile games.
This looks to be their most ambitious title to date by far. Going by past releases, it's likely coming to PC at some point as well if not at release. No publisher has been announced yet. I'm sure if Sony were publishing it, they would have announced that during their event.
Wish them luck as this looks promising.
