Like friendly said, but on a more serious note, they've beein' doin' Mergers; that is development. Jus' because some people don't like it, or because it doesnae affect other servers doesnae mean it's not involved.
Most games don't come out w/ patches or game updates regularly; you typically have to wait 9months~1year+ for new versions to be released on a game for any extra content updates and they have announced Age II, which is supposed to be a massive update.

Mind that on other MMOs you feel like you're gettin' content regularly 'cuz of weekly patches where they release new CS or w/e for sale, or some promotion, but it's not game updates; jus' other things in the CS. Evony doesnae always do that so it feels like nothin's changed. It's jus' an illusion anyways.

Age II is supposed to have epic changes and updates and, as Rodri said, if they focus on gettin' that out sooner instead of givin' us weekly aesthetic crap, then I'm all up for that.
