I thought the part where Orochi summoned the 1st and 2nd Hokage's was a bit overdone for my tastes. If Orochi is more poweful than all those Hokages, then it's understandable... but he has to be pretty damn powerful to summon 3 Hokages in an instant with ease.
Either that or:
1. Hokages arent all that strong.
2. the summons arent as strong as the real thing.
I honestly dont know how powerful any of these guys are, so im in no position to jump into any conclusions.
It's just that i would only expect sumthing like this from the last mother boss at the end of the series, being it's THAT good a technique.

I'm also anxious to see what Shino has in store. We've hardly seen much of his abilities, and i bet he's really strong since he knows everything thats going on and dispelled the genjutsu. Though he never really was one of my fav characters, i can't wait to see what he can really do.
