The update is needed whether it will be fantastic or not. As a staff point of view it's very much needed and will make it a hell of a lot better and easier for departments who use the site. (News, RVR, HxHD, Content, HabboxLive etc etc)
From a non-staff point of a view: To add new major features to Habbox, we also need this update. Due to the fact that V6 is a headache for everyone.
Might have been but it was a big jump from the Joomla software. You also have to think about the backend.
