The new opening contains the following:
- Strawhats vs. Pacifista
- Hancock and the Amazon community
- Every Warlord, including Jinbei
- Luffy kicking ass in Impel Down
- Luffy and Ace in a dramatic shot in which they're separated by the burning vivre card
- I think it also had Magellan and Hannyabal, but I'm not sure
And yes, the opening was epic.
