Personally, not likely. Seeing as the sauna event (from the last teaser) is when things get hot, I don't think there'll be anymore teasers until update release. If we do get another teaser it might be a post-event picture of what happens when Ellie, Sophia, Logan, and Tyler are done with their time together.
If you want out of this world speculation, the next teaser might be what the event will look like on the Ellie x Sophia lesbian path. (Though highly doubtful since that one might be a long one too and will need it's own update.)
