I'm a supporter, but I also have my limits.... An extra month of d20pro isn't quite enough bang for the buck for me. Especially since the roadmap that's been up for months states 2014 for almost all of the items to be implemented whereas the release is slated for early 2015 at the earliest which means summer more than likely.
They need to make pre-release a this-year affair for me to bite that bullet.
I do agree with you on that point, but on the flip side, it is nice to see a RPG project where the first decent backer level is <$100 (and in this case, well under!).
