As unearthed by our very own John Polson, Super Meat Boy Galaxy is, and I quote, a 'completely unofficial 3D version of Super Meat Boy' that was made for a very lucky individual's 30th birthday. Sadly, if the description on the video is any indication of things, a release of this rather well-done training exercise is not something we're going to see. Still, this is a prime example of what you can do with Blender, Unity and many hours of focused effort.
