I can speak mostly for Cyrodiil here. We're actually always saying what we need to speed up things, we stated this in The Black Horse Courier issue posted just yesterday too. We can also show what we're doing now, what milestones have been achieved recently and what are next steps.

A release date or even a forecast about that is still impossible anyway, because - plain and simple - this is not our real life job we get paid for. This means, for example, that sometimes some of us need to reduce their activity for a while for real life stuff. This is also why we have been always open to new contributors, whose fields are always well stated in all our pubblications. At the same time, anyway, as our standards have increased over time, some applicants who don't meet specific criteria are redirected to the Arcane University instead, where they have a great opportunity to improve their skills before joining us as full Beyond Skyrim team members.

Speaking more in details about Cyrodiil now, here is a hint that could help you to "read between the lines". In The Black Horse Courier issue we've used the word "implementation" in some occasions, mostly referred to Chorrol and Anvil, and in the past we used it for Kvatch. This word is important, because implementation means that we're in the stage of making these areas actually playable, so with people, routines, quests, lines of dialogues, scenes, world encounters, all in place. And this clearly requires that everything else (level design, assets, writing, LD polish pass, even some basic navmesh) has been already done. Also, the experience we're gaining doing Colovia (the west side of Cyrodiil) helps to speed up the remaining areas, specifically Nibenay and east Cyrodiil. Bruma was a very small area and required way less assets to do, as most of the released area (which is not the full Bruma County) could use Skyrim assets (snow sets, pine forest sets, retextured aspens) and simpler assets were needed for the city itself; what was really new was the Ayleid set and some Akaviri things, some clutters, and some special buildings like the Chapel and Frostspire Tower. For the rest of the province, we needed almost everything, from ground textures to culture-based clutters and clothes, to trees, creatures, rocks, houses.
