I will be releasing Outremer Friday, July 1st. It's ready to go, and I have an advance print copy from Lulu and it looks nice. It's fairly large - almost 300 pages, but it's not, I think, bloated. It just has a lot of setting to cover. There are name generators, lists of titles, clothing, timelines, and other space-taking but important things- important for setting flavor, that is.
With the probability of an Outremer Companion in the future, I don't see any reason to wait any longer. The Companion(s) will be covering a lot of peripheral stuff that is cool, but not essential. I hope to write a few articles myself, but the best thing would be articles submitted by folks out there.
