I agree that we do need all the versions of Naruto and Sasuke, but they're shoving them in our face at the moment.
I've come to like supporting characters more in Naruto, and I was a huge fan of Kiba and Neji when I watched the Sasuke retrieval arc. To see them get spotlight was amazing, but I really became a fan of all the Sound 4 during everyone's matchups, especially Kimimaro, Sakon, and Tayuya. So basically, I love their style alot.
CC2 won't give us Sound 4. They're bound to be in the game, but I highly doubt as playable. They'll take the lazy route and make them support which is ridiculous considering they're the base of an entire arc just like Zabuza and Haku. CC2 Also left those two out in Storm 1. That's why my hopes are low.
Another thing, they update Naruto and Sasuke so much, but so far we haven't seen anything about the rest of Taka. They aren't main characters, but they should atleast have new clothes and Jugo's new awakening. Will they have the awakening? Probably, but who knows. It's the little things that make a difference for me.
I'd rather have Jugo's full version 2 state, which some if forgetting, than Naruto's Kyubbi mode, which is taking all the spotlight. The Kyuubi mode is awesome, but I want more little things than one big one.
