Passage: The DVD and Blu-ray release in Japan took place on May 26, 2010; unlike the 2 DVD versions of 1.0, it was released as 2.22 with "readjustments". Universum Film's German release was on September 17, 2010. The Japanese release set an Amazon.co.jp record for pre-orders, with more than 88,000, and ultimately over 800,000 pre-orders in general; upon release, it set first-day sales records (124,000 DVDs and 195,000 Blu-ray discs),  topping Blu-ray sales for 4 weeks. At Otakon 2010, North American anime distributor Funimation Entertainment announced that they had licensed Evangelion 2.0 and would plan a theatrical release followed by a DVD and Blu-ray release on April 5, 2011. The release date was later brought forward to March 29, 2011 for the United States, but the original release date was retained for Canada. In May 2010, British anime distributor Manga Entertainment had announced plans to release Evangelion 2.0 in the U.K. and were waiting on Funimation to announce production dates; in December 2010, the release dates for the Blu-ray and DVD of 2.22 were announced to be June 2011. Later, the date was changed for an early release on May 30, but then finally pushed back to the original month, on June 20. Australian distributor Madman Entertainment released Evangelion 2.22 on Blu-ray and DVD on June 15, 2011 under exclusive license from NTV & Manga Entertainment. This time, Madman's DVD included all special features on the one disc, unlike its DVD release of 1.11, which came with one disc (whereas the North American DVD releases of both movies have two discs) and missing some special features (the Blu-ray came with all intact).
