Dragon Quest Builders is a Minecraft clone with RPG features

The Vita is already getting a DQ game in the form of Dragon Quest Heroes II, but Square's coming on strong with a Minecraft clone/rip-off in the form of Dragon Quest Builders. It will also land on PS4 and PS3, so there's hope for some Cross Play.

There's only a teaser site, and a single image for now. I don't see a Mojang logo, so its not a licensed version - what are the chances of a Microsoft law suit?

I guess making a proper RPG in this type of blocky environment is differentiation enough, but surely smarter developers will be moving on from the block-based approach and coming up with a new angle?
