Pat, I wasn't really serious with the ECW; I'd like it, yes, but I can think of (at least) 10 other sets I'd prefer (all of them WW1 British).
I also think it's great that HaT have overcome their difficulty and are starting to make figures again. Even if the ones they are choosing, such as anything ACW, just send me to sleep. That's fine. All the projects will get done, as long as the crowd funds them.
But you've spotlighted the brilliance of crowdfunding - there are a lot of people who talk a lot about how many brazilians of sets they'd buy of this and that, but crowdfunding cuts out the chaff. If the set isn't popular enough it doesn't get made. End of story.
