My theory remains the same and I posted it back when the update came out. And that basic theory is that the IRL sexual intercourse is probably in a later update. Earliest would be March is my guess. I would be immensely surprised if something crazy were to happen in the February update. In terms of Asuna content, it's going to probably be one of the weaker ones, unless Fujino was planning on adding an Asuna/Inoda POV from the cave/maze part of the latest update.
But I suppose in theory I'd guess the next update would focus more on Sinon/Suguha, because Asuna will have a more token effort this time? But who knows, I can't reliably say Asuna would be given a token effort, because Fujino might make a lot of CGs with Inoda regaining a lot of IRL ground so that by March or April, they'll be banging again. The time period when they'll bang IRL is probably in-game Sunday, since Fujino likes to do the major progressions during in-game weekends.
There was a theory going around that Inoda will use the recent FOG events to make Asuna do Anal in FOG. I give that a 50/50, because I feel like it could be either Fujino wrote that in for Inoda to focus on IRL progression, or wanted to give any reason to go Anal.
In terms of the ritual stuff, my thoughts about it stay the same. Either Yui is going to be nerfed, distracted, changed, or hijacked by the Administrator.
But anyways there you go for theories
