Alicization was originally written, and finished, as a web novel around 2008. That marked the end of the web novel version of SAO. The light novel version being published currently is following the web novel pretty closely so far, but it's up in the air as to how Alicization will end in this version.

All in all, the plot looks to be heading towards the same ending so far.
