They have always been separate updates. I wouldn't expect R(h)onda's update for at least 3 to 4 months after the tech update. Could be less than that, could be more. Depends upon how many bugs are reported after the public gets the tech update. Also, even though the artwork and script for R(h)onda's update is probably near done, the coding and the posing most likely won't even be "started" until after the coder and posers are done with the tech update. The items you mention in your post are not in the original goals for the tech update.
The art was changed from 4:3 display ratio to 16:9 for better use of mobile screen space (as well as modern monitors). The code is rewritten/edited because it was a frankenstein's monster assembled by over half a dozen different coders over as many years. And other things.
