Yes basically its just the 6497 top hand wind movement, no swan neck. And I agree if not better!
I think the key to repping this will be the usual issues rather than the movement, I think its best to stick the basic rep OPI. And concentrate on all the other flaws. Just think if they got this one right it would basically open the flood gates on a whole range of decent OTB rep PAMs A forlorn hope for now I think!!
Its a shame though given all the hype on Risti in the build up to production.
But I guess the argument was for a roots (618 etc, etc) based PAM
