Kingmakers on consoles
Consoles are planned, and later. The studio’s first answer tied them to the finished PC version; the game director’s more recent one names PS5 and Xbox as targets that will not arrive with the first Early Access release, and adds Switch 2 as a maybe. No console has a date, a store page or a port announcement.

Every console, one card each
Two answers, years apart
After 1.0 on PC
“Yes, it is in our plans to release on consoles eventually, but only after 1.0 is fully released on PC.”
Official FAQ. From the Kingmakers Official FAQ (Steam discussions)
Version 1.0 is the end of Early Access. The FAQ also says the length of Early Access has not been decided, so this answer cannot be turned into a year.
Targeted, not at first launch
“I know we were planning to target xbox and PS 5 but not for the initial EA release.”
Paul Fisch, game director, on the Steam forum. From Paul Fisch on consoles, Steam discussions
This names the machines but not the timing, beyond ruling out the first release.
Read together, the two answers do not conflict: both put consoles after the first PC release, and neither says by how much.
Switch 2
“It would be really cool if we could get this to run on the switch 2 as well, and I’m sure we will try, but I don’t know for sure if we will be able to get it to run well enough on switch 2 to justify porting.”
That is an intention to attempt a port, with the performance question stated up front. It fits what the studio has said about the game elsewhere: it was delayed partly to hold a real 60 frames per second on mid-range PCs, as covered on why Kingmakers was delayed. The original Switch has not been named as a platform in the studio’s announcements, FAQ or forum replies.
Why the showcase did not settle it
tinyBuild’s showcase press release, the one that announced the gameplay deep dive and the playtest, mentioned console versions of some of its other games. Its Kingmakers section did not mention consoles at all. Until the publisher says something, the forum answers above are the whole record. Game Pass has not come up at all; that answer has its own page, Kingmakers and Game Pass. The full platform board is on Kingmakers platforms.
