Imo, he should start a kickstarter and see how that goes! Imo, Kickstarter games seem to get more press (?) than say, twitter signatures and people are also putting money where their mouth is! Heck, someone even pay thousands of dollars by themselves if they really want it to be made.
In any case, it sucks but I do hope that they don't quit on it completely!
While I do agree completely (and other devs have found GREAT success from this *see Mighty No 9) he already tweeted that this wasn't going to be an option. Why? I have absolutely no freaking idea, but it is what it is.
