I personally doubt this has a torso.
Its obviously possible but sideshow will know most people will buy this to go with there other terminator busts which so far ( arnie being the excpetion ) have ended at the neck.
The Terminatrix , t-800 bd and the clean endo.
To have them all lined up and then another with huge shoulders wouldn't really make sense.
The photo on the teaser video could confuse some that the piece has shoulders since the T-600 design is very bulky and the neck is shorter and wider than the T-800's.
That makes the impression that what your looking it is shoulders where in fact its only the neck.... which I think on the bust itself will then lead to the base and plaque with the name on it just like the other busts.
At least this is what I'm hoping for anyway. It would certainly create the best display this way if you had some or all of the other busts.
The fact that the T-600 is actually bigger than the T-800 gives another reason it should end at the neck because if it was any bigger it would start to look too big ( even if accurate ) compared to the others on display.
