The contest rules seem to suggest winners will be announced in June, but I imagine there will could still be editing to be done after that, plus all the other preparations that need to be made prior to publication.
Plus, even if all of the entries are completely ready to go without editing, I imagine CoG/Hosted Games will not want to publish twenty five titles all at once. That wouldn’t make a lot of sense as a marketing move. So I imagine we’ll probably see a steady trickle of releases after the winners are announced. I wouldn’t be at all surprised if we don’t see some of these until next year.
Whatever the results, I’m really glad this contest gave me the motivation to finish my entry. Congratulations to everyone who submitted, and best of luck to all of you.
