Okay so that's not a question, but more of a something about sao, so far from what i've seen, they follow the web novels and i've read them so i can tell you stuff about what'll happen later in the novels(like for example i know the end of the plot of sao assuming they end it where the web novels ended).

The web novels only ended where they end because that was where he was at when they were published.  So it’s not necessarily the end of the series especially since the web novels end in a cliffhanger or sorts.

There have also been some major changes in the light novels from the web novels so nothing is certain.

Personally I’d be fine if the dark territory arc was the last main SAO arc and he had time to write 3 Progressive novels a year.
