As a pianist I can say that I like this idea but it is definitely not new. What he's doing is standard piano technique that's been used for centuries. The only thing new is that he ONLY does that. Usually you'd have a passage like this and then move on.
I do like the idea I have to say, though if people can bare to listen to it for more than a few minutes we'll have to see. It will be difficult to keep such playing interesting.
As for the acrobatic aspect, I don't find that impressive. Any trained pianist can get his or her hands over repeated arpeggios, put the pedal down and create a blur of notes - standard requirement.
