According to the video, Sense 5.1 adds statusbar toggles back. Hooray for that, that was standard in Sense 3, although they've been somewhat rearranged if that vid is an indication.
I'd expect some other Sense improvements along with this, they've had time for plenty of feedback from One users for areas to improve.
Butterfly users are feeling the sting of no longer being on the flagship phone (and others are feeling some strong update desires), so it makes sense (no pun intended) that they're preparing a broader update, not just for the One.
