Square Enix confirmed last night that the Kingdom Hearts series (minus melody of memory for some reason) are releasing on steam June 13th. The trailer (linked below) was released this morning along with the relevant steam pages for each of the games.
Kingdom Hearts 1.5 + 2.5:
Kingdom Hearts 2.8:
Kingdom Hearts 3:
The steam pages tout updated textures in Kingdom Hearts 1.5 + 2.5, as well as Dream Drop Distance HD (included in 2.8) the system requirements are also higher for these releases then on Epic Games which indicates that these are brand new (probably upscaled) textures. Steam achievements, cloud, as well as input API all appears to be included. No word on the steam deck but rumor indicates that square specifically hired a team to ensure steam deck compatibility (a major selling point for me).
