Teasing a new feature (or a new thing?) without saying what it is, is bad communication. I don't see what could be "worth" it. Certainly not delaying the overall progress of the VN. Even if it's animation, it would just be catch-up with other VN. Worth for some people but nothing to write home about in this days.
Even if the quality of the renders go up, it's not worth for me if the progress slows. The quality in this game is good enough already, top tier. If you want to look at super pretty images, you don't play a VN. Story comes first, otherwise you make image sets and not a VN.
