Prince of Persia 4 leaked video?

This most probably cellphone-recorded video shows a model supposedly from the upcoming Prince of Persia 4: Ghost of the Past, which was repeatedly rumoured (and unofficially revealed by UbiSoft themselves through an artwork). It's exactly the similiarity to this artwork that may prove this video genuine: notice the arm/glove that Prince has, one that might be distantly inspired by Dark Sector and/or possibly Bionic Commando. And given how the Jerry Bruckheimer's movie is nearing, this may as well really be from the upcoming Prince of Persia videogame..
