I bet you Naruto's new frog-sync technique will be used for this filler's finale and that only. I guess that's a good thing, keeping it all contained.

I agree with whoever said Sasuke's grown up to be an even bigger douche, but that can't be helped. During the last arc of PreShippuuden, he's already arrogant at how Konoha was no place for him. The last three years he's been treated as princess, being the one directly under Oro (literally the case in fanfics), and most liklely on equal footing with Kabuto.

It doesn't make this any more enjoyable, but at least it makes sense.

Hopefully his test is something awesome directly out of the manga.
