My guess is that there aren't any updates coming. The most interesting part of M.O.E., from my perspective, is the main quest delayer. Several years back I did use it, but switched to Alternate Start when I reinstalled Oblivion.
IMO one mod that is missing from the community is a truly great main quest delayer. I do believe that there is work being done, as part of the Prelude Kvatch mod that is in development, on a new main quest delayer. So even if MOE is not updated, hopefully there will be a great delayed start mod (with Kvatch, the Emperor, etc.) released at some point.
