The following image was posted by Arnold (or his staff) to his official Instagram Account. We see Arnold wearing the same wardrobe as seen in teaser images, tight dark T-Shirt and the new trademark T-800 with grey hair look.
He can be seen in what looks like his personal trailer, most likely on the set of the new Terminator movie currently titled Terminator: Genesis.
He is stood with boxing legend Evander Holyfield. Is Holyfield just visiting and having a look around the set or is he there for a reason or a cameo? Who knows… the enigmatic mystery movie shoot continues…
