Just a quick announcement that I've uploaded a video showing off sort of the status of the next update. It's up there next to the teaser trailer and all the screen shots.
As you can see from the video we have the core engine components and upgrades working, but there is a lot of polishing that still needs to be done such as fixing icons and UI elements etc.
This should serve as an indication that we are switching to a new development phase for the upcoming content update. It has moved from the design phase to the testing phase, and we will prepare it for release once we feel confident it doesn't make the game worse.
