Sure hope it turns out to be true. If only there were some pics of the actual figure in its packaging with all the pieces in their trays, that would be very helpful right about now!
It also says Hot Toys. That usually means buyer be ware. I'm with Mudshark. There's something lost in translation in the items' descriptions. While I would like to hang my hopes on the use of the word additional, I'd rather hang them on additional reassurances.
When all is said and done I suppose the present uncertainty about what we're getting will be soon forgotten, but it would just feel a lot better knowing beyond a shadow of a doubt that we'll be getting the whole enchilada, and not the shaft!
I'm not too worried about it. I'm in the camp that thinks the Exclusive will come with everything + bio mask.
The example that comes to mind is Hot Toys Robocop v.1, and Robocop v.2. Sideshow had both available at one time, and both where identical in every way, except SSC had listed the v.2 as a "SSC Exclusive with Gunarm."
