I know there is some work being done on at least one new tablet that could possibly ship pre-installed with iodéOS, and also some work to expand the supported Samsung tablet compatiblity. And I do make an unofficial Pixel Tablet build, which I think they are considering officially supporting.
But also good to know that the new OnePlus tablet is supported by LineageOS that may be a good one to target as well, thanks for the heads up I’ll pass to the team.
