Men In Black Trilogy is a combo giftset which features all three movies on Blu-ray along with Ultraviolet Digital versions. It is due for release on 30 November 2012.
A Canadian edition is bilingual (French/English) and has different packaging. Amazon suggests this comes with DVDs but cannot find any evidence to support this. Looks similar to the German offering (see below).
There is an GERMAN version of this limited box set which is exclusive to Amazon.de and is already available. No digital versions, but it comes with the figurine and solid packaging with six postcards. The blu-ray discs are region free. See video below.
There is no special box for the UK just a standard set. Ordering the region-free German box would probably be the recommended route if you want the gift set.
