Hasbro just sent us word though...
Even what they say is rumor, and you really shouldn't expect this to be confirmed till you physically pick one up in your hands, and are allowed to purchase it at a retail counter... The statement from Hasbro read that there's rampant rumor and speculation to the point that they believe even holographic projections are being put out there editing AT-TE's into background images to imply one exists. Hasbro will not confirm/deny it... even if they say it's real, so only believe it when you actually get one.
Much like Target's Ultimate Battlepacks, trust noone, and believe it only when you see it yourself first-hand...
Even then, make sure it's not a trick by some prankster putting a full sized custom on your local store shelves.
We dont' want this getting out of hand guys.
(sarcasm above, enjoy)
