I asked this question in their Take about the last update and this was the response of an admin: "We are still in a development phase... We make changes to better suite to users' needs. However I can tell you that this was the last big update for sometime to come. But do please give your feedback. We'd like to know how you want to use the site, how and what content you want to see. So keep it coming "
So there's not gonna be a major update soon, and obviously it's not gonna go back to how it was.
If the site went back to the way it was before it would be a downgrade, not an update. A update is to make further improvements. Admins are always finding ways to improve with site and add new features, so I'm pretty sure in due time there will be more changes.
