Minecraft on Wii U is nice, and since Nintendo content has been promised (according to Nintendolife) I'm considering getting it over just playing it on my PS3. The price is ehhh but it beats buying more PS3 controllers.
What's kinda weird to me is that Nintendo has it listed as 4-player local instead of 5... Which may mean you can't have one person on the TV and another on the gamepad, or it's just capped at 4 because of hardware limitations. It'd be a bummer if you couldn't...
Another thing to note is that every version of Minecraft to date has had a demo. If you're on the fence chances are pretty good that you'll get to try it on release.
The Nintendo content... At worst we get Nintendo themes or amiibo costumes. At best, we get custom game modes with the themes that change the game to function more like Mario, Zelda, Metroid and the like. Which admittedly is a stretch but it'd certainly bring nonfans over to Minecraft.
Also Steve in Smash.
Actually after Cloud I'd say his chances wouldn't of been bad without Minecraft on Wii U, between the ballot and how big the series is. Now he's probably more likely then Shantae and Shovel Knight combined.
