If authentic, it's clearly an early image, unless this new Prince has the ability to make bystanders hover. The name "Prince of Persia Zero" has been used internally as a name for a reboot. Former art director Jonathan Jacques-Belletête used the name in an interview with CVG, in reference to either the released 2008 game or a cancelled "modern" spinoff (it isn't clear which reboot he names as such in the context). In either case, "Zero 2" would suggest another spinoff or reboot.
