I hope they also included the sculpted neck so he looks more like this
What do you mean by included it, you mean added so the neck and head are one piece not two or do you mean that the neck piece will be the one with unique Palpatine sculpt details? If it's the latter, I can't see why they wouldn't, the prototyped itm if they were going to cheap out they'd have done it before, it'd piss off a number of customers to not include it.
