I think the only three we don't have art for on that list yet are Stormbreaker, Kotetsu, and Dream Girl.
After those, I'm going to probably launch the first issue as a PDF-only book. I'll tunnel ahead with the other characters as PDF-only books until we catch up/overtake the player-submitted stuff. There are some folks who still haven't turned in their stuff, so we'll have to sort that out, but the goal is to fill out any 'blanks' with fun articles from authors like Jack Norris. The first book will have a great article on running a campaign with villainous player characters...
Once I'm back from Gen-Con I should be able to announce a solid character list for the first book, and then make further announcements. I do plan to turn this into an ongoing series if people are interested in having more characters entered. There may even be a tie-in with an upcoming kickstarter I'm planning for after Gen-con, too. We'll have to see how that works out, though.
In any case, we're looking forward to getting the colored pieces back from Dan Houser shortly, and I'll be posting the images over at the Vigilance Press website and keeping everyone up to speed on the progress of the layout once things get to that stage.

Thanks for staying interested, I hope the final results are worth the wait... I'm certainly really loving the artwork that Alex has turned in so far!!
