And again, the thing is that these endings were planned/stated BEFORE Suguha's plot was changed, which is one of the first things I pointed out, the endings were planned back when Part 2 was beginning, and Fujino went through a lot that clearly made him change the plot dude, I've been here from the times of Part 1 so I have seen it all happening live (For example, Suguha very obviously was gonna end up Hebishima's sex slave originally, most likely having threesomes with him and Sinon...and then Fujino put things up to vote and the "get rid of Hebishima" choice came up, thus changing the whole of her plot and her interactions with the main plot).
The thing is that the endings Fujino has established do NOT allow for Kirito to "move on" or "be happy" at all, which is why hoping for new ones is the only thing if you want him to have this In one ending, he won't know Asuna is cheating on him, so he will keep being obliviously NTR-ed forever. On the other, he will get off seeing Asuna getting fucked by Inoda, and be 'happy' doing that, so yep. The only possible alternative is, as I mentioned, that Fujino hasn't brought up the endings ever again since back then and it was before he did all the changes he did to both the main plot and the secondary ones, so things could have changed since then, but at this point we don't really know.
