We're officially adding the Wuxing faction (designed by Kevin) to the roadmap with an intended November release. You can, of course, see the Wuxing faction in development herein our forums as Kevin has been very public about updates and playtesting. A November release means getting files to the printer in early September, so the next three months are critical.
This is going to be a very challenging faction to do in terms of art, and it's possible that a replacement unit will have to be made on relatively short notice. If so, I hope you'll all jump in to help with playtesting.
And, of course, if you haven't played with the Wuxing yet or have some particular things you'd like to test, by all means jump in and give Kevin your feedback now.
All the best,
