Doesn't make sense, because everything looks real, other than the face. If they could create the whole body, the finger movements, etc. so fluidly (it really looks like a real person dancing), then why couldn't they create the face as well that real looking? It looks horrible - and it really looks a decade old.I am not that into computers so I don't know what is possible and what not. But when you watch movies like Transformers it's pretty much everything possible. And even more in the movies there are more complicated stuff and characters doing more complicated moves that this "MJ" performance and it is even more realistic.
So what I'm saying is that it is possible that it is created entirely on computer. I don't know. Either way it's not Michael.
The CGI of the face looks a lot like The Mummy Returns 2001
