1) I'd wish that the series is guaranteed to have an awesome ending, just incase there's a chance the ending may completely suck after all these years of following it.
2) I'd wish for an amazing Naruto game, following the series from start to finish and packed with over 100 or so characters, each with their own fleshed out move-sets. There would be tons of customization options, zero filler missions/side-quests, and it would be a mix of all the best things from the Ultimate Ninja/Ultimate Ninja Storm series.
3) I'd wish for a spin-off that showcases numerous characters fighting each other, and offering some more history about the Narutoverse. We'd see who really wins between Minato and Itachi or any other controversial match-ups, along with learning more about the Sage and his descendants, or history about some of the other villages.
