Honestly, I'm still at a loss as to why Minecraft: Xbox 360 Edition does not allow players to import character skins through some sort of PC wizardry. Creating custom skins for Minecraft is a basic luxury, but I digress. Mojang's answer to whatever issue prevents us from creating our own skins is the first of, I assume, many DLC packs.
Skin Pack 1, due out in the near future, features themed skins features Fable's Jack of Blades, Banjo, Ms 'Splosion, Gears' Clayton Carmine, and a nondescript prisoner. It's better than nothing, right? There's no date or price as of now, but I'm sure we'll be getting that info soon enough.
