The date only applies to European Vita owners, however, as no North American release date has been confirmed as of yet. We've reached out to the studio for additional launch information.
The PS Vita edition is a Cross-Buy release for any users who previously purchased Minecraft on PlayStation 3. Those who own the PlayStation 4 edition, which released just last month, will be required to purchase the Vita version as a stand-alone.
The next step for 4J Studios is a general update that aims to match all console versions to the current 1.6 PC build, known as the Horse Update. The developer confirmed this via Twitter, adding it "may take some time" before we can expect parity between PC and console editions.
