Update (Thursday, 9:00 PM) – Turns out the cover below is for the UK release. This one, which is only slightly different, is for the U.S. release.
The DVD boxart for Victini and Zekrom and Victini and Reshiram has been revealed, as you can see below. The two movies will come together in one package and will be released on April 3rd in the United States. Thanks goes to victiniEX for the heads-up!
