hmm... I don't think Ino pig is going anywhere. It's a possibility, but I don't think it's all that likely.
I think we're going to lose someone that will impact us on a deep level, but not significantly effect the story line. Such as Chouji, or maybe Sai. Though I wouldn't like to see either of them go. That's the point, of course. To take someone we will miss, but not be too seriously depressed about. Then again, I think if Sai died Kishi would be harassed by fangirls for the rest of his life. >.< so maybe it wil be Tenten? We don't really know her all that much, after all.
Maybe none of the chunin will die. Perhaps these deaths will be older adults, their parents are all likely victims. I hope they don't kill Shika's daddy. He's so awesome. Lol. How about Ino's dad? He's cool, but Ino needs a reality check anyway.
