>The Platinum outfit (as a pre-order bonus)>The Rotom's room at the Team Galactic Eterna Building>The Gracidea lady from Floaroma Town>The E4 use their Platinum teams during the first rematch>All of the PC box wallpapers from Platinum are present (but Charon was removed from the Team Galatic one)It's all pretty arbitrary as you can see, they obviously know Platinum was the true definitive experience but are content with giving the original vanilla version because realistically that's the one most people actually played, Platinum barely sold half as many copies as DP (because third-editions aren't really "new" games thus aren't as exciting)
It's even possible they would go as far as release a standalone Platinum remake for the sake of being "faithful"
