We have no official information about Digimon Adventure tri. part 1's US Blu-ray and DVD release minus an off-hand comment about why the UK release was delayed.Now we have a bit more.From a tweet from Jerome from Manga UK , we now know that the American release of Digimon Adventure tri. part 1 in the USA will be a week before the UK release (contractually they have to release later to have access to the dub.Based on when American Blu-ray and DVDs are normally released, this means we can (likely) expect the release on March 14th if nothing changes. Assuming the information is correct of course, which it seems to be... especially since he later mentions saying it seemed to be based on a misunderstanding with the US distributor (so hopefully we get an announcement soon.)Thus far we don't know what company will be releasing it, or if the release will be done in a similar way to the UK release (a collectors edition on Blu-ray, etc.)News about the UK release of tri. part 1 is here
