It appears that AH has substantially stopped publishing new games under its new owners: http://wizards.com/default.asp?x=contactinfo/submissions reportedly says”

“In light of recent changes in the Hasbro and Wizards of the Coast product lines, Wizards will no longer be publishing games or accepting submissions or ideas from independent and unpublished inventors. In short, our department for publishing these kinds of games has been dissolved. This means that we don't plan on releasing any board games, family games, toys, accessories, or non-collectible card games in the next few years.

We realize that independent inventors have a lot of time, energy, and talent to contribute to the gaming industry, but financial priorities have led us to focus on a few big products at the expense of many small ones. We encourage you to pursue other avenues of publication.”
