Thanks. Indeed, Minecraft could be awesome on WiiU. But I wouldn't hold my breath for it. I'm quite used to such awesome things not coming to gaming platforms of my choice.
Also, I heard somewhere that only Microsoft has the rights to this game coming to a console. It's definitely possible, for that's what they did with Super Meat Boy. I asked Team Meat during a live Q & A deal if they would consider porting Super Meat Boy to Nintendo's next console, and they said no. One of the reasons being contracting issues.
