Minecraft will be available through Xbox Live starting on Friday, September 5th. The normal $19.99 price is chopped down to $4.99 if you own the game on Xbox 360. 4J Studios said in the past that this discount will be offered for the next year, in case you're not in any particular hurry to upgrade.
Your saves and DLC packs from the Xbox 360 edition will transfer to Xbox One for no additional charge. The developers hinted in the past that some DLC wouldn't carry over due to "licensing restrictions." However, leader producer Roger Carpenter said today that all content packs will be transferrable:
"ALL downloadable content players have purchased for the Xbox 360 Edition is available free for re-download on Xbox One" #MinecraftXbox1 :)— Roger Carpenter (@PopsRamjet) September 3, 2014
4J Studios is also putting the finishing touches on the PS4 and PS Vita versions of Minecraft. The PS4 edition was actually submitted for certification before its XB1 counterpart. However, Sony found a few bugs for the developers to fix before it can be released.
Minecraft PS4 wasn't included in the European or American PlayStation Store updates this week. Mojang's Daniel Kaplan says that the PS4 version could actually be out before the Xbox One edition debuts, though. In fact, it might be here by the end of Wednesday:
We're working out some last minute things with Sony and hopefully later today you will be playing Minecraft PS4 on your ...PS4! :)— Daniel Kaplan (@Kappische) September 3, 2014
And that is for EU and Americas!— Daniel Kaplan (@Kappische) September 3, 2014
The PS4 version has the same price and last-gen discount as the Xbox One version. Both platforms allow players to create worlds up to 36 times larger than the PS3/360 editions. The game supports four-player split-screen and eight-player online sessions.
The Vita edition is closely based on the PS3 version so won't have as many bells and whistles as the new-gen releases. However, it's going to be free to people who own Minecraft on PS3 so it's got that going for it. There's been no update on a release date for that platform yet.
