He's dead, tsunade is a legendary healer, she has a shocked face, and then a sad face, then when she says choujis dad is alive and chouji says "and what about kakashi?" and again with a sad face and silence.
Shes a legendary healer, narutos heart pretty much stopped during the 3 legendary ninja fight when he got caught up in the crossfire, so she is capable of bringing near dead or pretty much very newly dead people back to life, this one she doesnt appear to be too happy about, suggesting its out of her hands.
The guys dead, if he is alive it will be because of something corny, which will certainly be a happy moment for the people who dont want him dead, but itd be a lot nicer to simply have tsunade heal him than have 10 chapters of corniness.
