Yea. I think it is actually going to be a ROTJ helmet. You can see in the reflection in his eyes the really pale looking skin which is probably ROTJ Ani. rather than ROTS Ani.
Plus the two tone paint scheme suggests it's going to be ROTJ.. I think the dome is flared too much.. but it's hard to tell from that one pic. The paint could also be more glossy (or maybe it's my screen). The cape chain by his neck is weird looking, too thick and it looks like it's made out of plastic.
in terms of internals - from the two second shot that I saw, I think the mic tips by his mouth are too big, the silver teeth in the front next to his chin are too big. (chances are the head won't be removeable so you won't be able to see any more detail) the piece of metal with all the "teeth" - I think the teeth look too big, (but i'm just basing that off of the run that someone did here recently)
what I like about it is the fact that you can see those circular pieces in the back of the facemask behind all of the vents.
Gino - i'm just going to save up to buy your stuff... if you sell it.. if not, i'll have plenty of money soon to hire someone to burglarize your house.
Well, hell.. we'll see right? I'm not an expert on vader or anything... chances are my crappy statements about the sideshow vader are because I have two reveals and i'm upset that I won't be special anymore. (not that I show anyone my collection but you guys anyways)
