We are working closely with Sony Computer Entertainment to look into ways to enable upgrade from the Blu-ray disc version of Minecraft: Playstation 3 Edition to Minecraft: Playstation 3 and Vita. Well have more info on this closer to release.
This means everyone who has bought Minecraft: Playstation 3 Edition from PSN will get it on Vita for free. Those fluent in Sony-speak might refer to the deal as Cross-buy.

It doesnt matter if you buy for PS3 or Vita first, you own the game for both platforms.
Saves are transferrable between the Playstation 3 and Vita versions of Minecraft. You will be able to craft at home on your Playstation 3, then continue on the bus/toilet with your Playstation Vita.
