That is true. Most of the feature is not eclipsed (If you know what I mean).
Sta.sh writer is no longer a thing, Group is still on green site, and some of the features they promise are not in Eclipse at this moment. The profile is still a mess, the UI is sometimes messy (though it okay at most part) and progression is damn well slow. 2 Years of working on this and 70% features are not in it, yet they decide to push it to be the "New" Deviantart.
DA is a new Digg at this point. They should take a lot of time to make Ecplise least something more useable.

DA just shot theirself in the foot with Eclipse update. It no surprise people are leaving that site after getting ignored by the staff that doesn't care about user options.

They apparently didnt even work out the kinks in it any of it! According to folks, stuff like Notes, Stash, and Groups still use the old UI and mobile is missing features.
