Anton, I think the TE Tank Gunner's what we're getting at this point... So late in the game, the items displayed looked like production stuff to me, but they could surprise us.
I too am a bit disappointed at the TE Gunner being included, should that be the case, as he's not the best sculpt overall. The legs are his only benefit while the rest of the figure's a bit unposeable. I look at the sets more for the Sandtrooper at this point, and the Clones are just gravy. I'd have rather gotten a SA Clone with a removable helmet than the TE Gunner, I agree... I think we're getting TE Gunners though unfortunately.
