I have seen in a video by the Wargamer guys out of Poland (the By Fire and Sword rules and figures) that they are going to Kickstart an ECW game this summer.
They did a fantastic job with the rule book for By Fire and Sword, the rules while good are nothing really new but play well and the way they have the skirmish battles set up it is quite fun.
They do lots of different nations and you can create a variety of forces using the army lists.
I think this would all work really fantastic for ECW. An added bonus is that their figures are getting really good, the new ones are as good as some of the best 15mm figures around.
Looking forward to this.
