I agree with you Justin, the foundation for a heel turn is there. But instead of building up to it (hell this feud been going on for half a year what's another 2 weeks) they went with the "Shocking Swerve"
What really threw me off was him costing the tag titles when Test had the pin then got mad at Stacy for costing the title which he actually said was one of the reasons he's snapping. Of course Emma reminds me that this *is* Scott Steiner he might have added that in by mistake LoL... I think you needed just a couple of weeks showing Scott more and more frustrated and detaching from Stacy then his snap would make more sense.
I can't imagine Chyna going over in a men's match in Japan. She got a lot of heat from the WWF men (remember Ahmed Johnson's comments in Mick Foley's first book), but Japanese puroresu seems even more chauvanistic.
