Sorry for the bump, but I didn't want to start a new Minecraft-related thread when there's already a pre-existing one.
4J Studios, the folks behind the Xbox 360 version of Minecraft,
confirmed the obvious, and stated that the PS Vita version of Minecraft will be using the same codebase as the Xbox 360, PS3, and PS4 versions, instead of being based on the severely cut-down Pocket Edition.
Aside from Lemmings Touch having managed to melt away my cynicism about it and how Sony has treated the franchise thus far (really, it's the first properly new, non-remake Lemmings title, since, what, Revolution?), Minecraft is one of several other games that's sold me on getting a PS Vita, so I was really happy to see that.
Also, since it's based on the same code as the Xbox 360 version (which I've been quite impressed by, on the occasions that I've gotten to check it out), that means character skin-packs as DLC. Bets on a lemming being one of those skins, anyone?
Ok, probably not a high chance, but there could still be one...
