As noted by What’s On Netflix and the teaser trailer, The Seven Deadly Sins: Grudge of Edinburgh Part 1 is currently slated for release on December 20, 2022. We say “currently” because that seems to be the goal, but not fully confirmed and subject to change. There is little to say other than that the plan is to get this film out so that the 2023 release date (as stated by IGN, currently TBA) for The Seven Deadly Sins: Grudge of Edinburgh Part 2 does not have to be pushed back.
Again, that’s Netflix we’re talking about, a studio whose current relationship with scheduling is in a drastic shift, so it’s possible that all of the above information could be completely undone at any time. As far as we know they could push Part 1 to next year and then release Part 2 in 20 minute segments over five months. Who is to say that?
