how many arc SAO haveThe only Alice CG that I remember being posted as of late was just a screenshot of a scene in the game, although we might be talking about different things.
It´s not that we are far from the end of part 2, it´s just that we have no clue when Fujino will decide to end things. For all we know, Fujino might decide to wrap things up in a jiffy and we see the climax of part 2 in just two updates. On the other hand, he might extend it for 4 or 5 more if he thinks RPGMaker can handle it.
It´s also important to note that Fujino never actually planned to divide the game into multiple parts, he simply ran into a dead end with the game as he went through the paces, so while marking the climax of part 2 and the beginning of part 3 with IRL sex might make the most sense from a narrative perspective, he won´t necessarily see things that way.
There might be a difference depending on how Fujino might want to approach a new build, he would most likely want to make a few changes to the UI and make new menus, and play a bit with the map and all that.
