According to the Best Buy website, Kevin Smith's Jay and Silent Bob Reboot will make its way to Blu-ray and DVD on January 21st, 2020. This release date should be considered rumor until confirmed by the studio via an official home video announcement.
There is no sign of a Jay and Silent Bob Reboot 4K Ultra HD release at Best Buy. That doesn't mean there won't be one, but the lack of a listing doesn't instill much confidence there will be.
Jay and Silent Bob Reboot features a massive cast including Kevin Smith, Jason Mewes, Melissa Benoist, Matt Damon, Chris Hemsworth, Ben Affleck, Rosario Dawson, Shannon Elizabeth, Joe Manganiello, Val Kilmer, James Van Der Beek, Jason Lee, Justin Long, Kate Micucci, Joey Lauren Adams, Harley Quinn Smith,
