we are not yet close to the end to give certain conclusions, we can not know who will be the winner, it could be Suguha winner, because that quiet quiet and in the end hits and wins, only Fujino knows how it will end and he could also change the idea, it is possible that some SAO fans told him that if he wants more fans, he should not limit himself to making the same endings for each game. NTR online is not like all the games that Fujino has made, lately it seems to me that he is trying to do something original instead of doing everything linear and that is the beauty
That's right it's too early to draw any conclusions, but with 60% of the story already told we can guess how or if it will end.
He changed the main plot toward the Council, he is giving more space for secondary characters plots like Sugu or Sinon but with the Inoda/Asuna plot he has been quite consistent is the same since the beggining, with some adjusts here and there but nothing major which means no changes to the original endings he already had in mnd.
The way the story goes so far points to Kirito ending up alone and oblivious to everything around him, or he being a voyeur cuck who likes to watch but don't do anything, and this can go with Asuna not even aware to the fact that he knows about her and Inoda. In this scenario is very unlikely Kirito will endup with someone else like Suguha, but her part of the plot is wide open for anything right now.
Asuna/Inoda/Kirito we going to get a real idea that how is going to end when Fujino bring the affair IRL, depending how he make the transition if he uses the reason that everyone already knows from the perk list he's not going to change anything in the endings, now if he came up with a different reason that could lead to new endings.
