The fact that this "prototype" was photographed with an iPad in user acceptance testing leads me to believe that it is old news. So what if it was only found in a bar recently? I'm sure Apple testers hang onto these things even after the usefulness of the prototype has elapsed.
The design is probably completely finalised and newer prototypes which more accurately reflect the final product now exist, it's just that no-one's found any of them in a bar yet...
