The next one down

[villain55]

I'm telling you all right now shikamaru death would be huge and unexpected

 

[Twin Steps]

I don't think anyone else from K11 will die simply because they're all safe.

Naruto, Hinata, and Sakura, are all plot-protected.
Kiba, Shino, Choji and Tenten's deaths wouldn't have much of an impact.
Shikamaru and Ino's fathers already died so they can't die.Also Shikamaru is plot protected.
Lee won't die as long as Gai is alive.

Like I said we need a "omfg that really happen" plot twist

 

[-Raviel-]

Hmmm maybe some useless f***er like Iruka

 

[Transcendence]

From the Leaf: Probably Gai. He'll probably open the 8th Gate and do as much damage as possible before dying and then in a resounding moment tell Rock Lee and everyone to carry on his will.

I doubt anyone from the K11 right now will die since Neji just died.
