Couldn't find another thread on this so thought I'd start one. Wolfgang Baur has announced the latest Open Design here.

This could be a 3.5/OGL or 4e adventure, dependent on who coughs up the most in support of their favoured edition. I'm hoping for 4e as they're just aren't that many 4e adventures out there yet.

Basic patronage costs $25 and gives you the option to purchase both Tales of Zobeck and the 4e adventure Wrath of the River King too. Being a patron is great fun and allows you to get inside what makes good D&D adventure design.
