Yeh, I guess I got used to the Gundam Seed Destiny openings where they spoil future events (and the Naruto openings where they heavilly hint towards the future events) and just assumed that events from the show's opening would be used in the show.
Especially since the opening ends with a Renji vs. Ichigo fight, which did in fact occur. Includes an Ichigo vs. Kenpachi showdown, also occurred. But the whole Hitsugaya vs. Ishida thing and Chad vs. that one Captain whom we really know nothing about (where Yoroichi does the badass act of biting off the enemy's sword, so wicked cool) were misleading.
Ishida IS already whooped, worn out from his fight against Capt. Mayuri. This new Captain really doesn't seem the type to kill, despite his words, and Ishida is obviously powerless so...
