Well, just about. We're waiting until we get updated with the 3.5 material to really declare the project done, but most of the rules are in place and aren't going to change, at the broad level. Once we get the intro chapter, credits page and 3.5 update into the document, it'll be done. Until then, it's mostly just the usable rules.
The final release will also have a smaller, graphic free version available.
