I wouldn’t be so sure about that. The season one set of RiD was released by Shout! back in 2016, but there’s been no sign of a follow-up set since then. Personally, I think they’ve lost interest - maybe the younger-skewing RiD didn’t have the same level of sales as the Prime releases? Meanwhile, Beyond Home Entertainment continue to push physical media releases of quite a lot of animated content that hasn’t seen a Stateside release, such as RiD, but also all of the post-2012 Marvel animated series that have otherwise not seen season sets anywhere else.
