In a dev blog posted yesterday, the studio went through the process of coming up with the ideas for a much improved Spacedock, including how it would be structured and what players would see: "A few solid points were decided. 1. It was all going to be on one floor. 2. We had to have a view both of Earth AND of the Shipyard. Point two meant that there was only one place for it. It had to be within the outer wall of the docking bay."
The blog also contains a link to an animated graphic showing a time-lapsed construction of one of the new areas. The Earth Spacedock revamp will come with Season 9's release on April 22nd.
