Wizards of the Coast released a gaming license for third-party publishers along with it’s 4th edition which was not particularly well-received. Now they appear to be set to change it, in response to numerous complaints.

From WotC:

“We recognize the important role third party publishing support plays in the success of the 4th Edition of Dungeons & Dragons. We have listened to the community and our valued colleagues and have taken their concerns and recommendations to heart. Our commitment to the health of the industry and hobby gaming lifestyle is reflected in the revisions to the Game System License.”
–Linae Foster D&D Licensing Manager

New license to be up in the “very near future”.
