Hi Plat.
Sorry to say bro, but I highly doubt that Kishi is going to put i a time skip any time soon.
I really just dont see any logical reason why he would benefit from it. First of all you cant have a time skip just before a War of that magnitude!
Why would he skip time, till the middle of the war, then we missed half of the important things that happend! Till the end of the war? What would be the use of missing the most important part of Naruto?
I dont see a time skip not until the war is finished, and that I dont think will happen soon.
If he wanted for Naruto to be more mature in the next time skip, he will not jump from 16 - 20 in a couple of weeks right before the war, no thats just stupid.
So I think that you are right. Kishi is doing a rush job to rap up the Manga. There is a lot of things that are un answered. I kind of see why he is doing that. He leaves the most important things out in order to create a bit more mystery, and then after the mystery have been unraveled in the manga, he throws those ideas important things that he deliberately skipped into a movie to make more money of us ; )
So I honestly see the manga ending end of next year. Max.
