I agree with Motteh.

the 4th GS opener was so cool, because
1. pairings flashed at beginning
2. slow build to small peak for the intro title
3. Realize was so let's-get-ready tune for me
4. the three druggies showing up & pulling back to show the Dominion (or the PS2 to Archangel's PS1, LOL), as well as showing Natarle as captain. that gave me "oh shit, she turns"
5. plenty of battle sequence, character profiles, etc

the last opener of GSD has to be just as good, if not better.
