I'm pretty sure BW2 moves won't be allowed, since they can't expect the majority to have access to that within a week.
That's a little bit of a lack of consistency. Does anyone here remember VGC 2009 in Europe? UK Nationals were one week after the release of Platinum, so all of the European Nationals took place on D/P carts. Yet Platinum move tutors were allowed. So if they think that people won't have access to that in a week, that's a lack of consistency.
Yes, I know Europe and the US have different tournament organizers.
