Sorry to necro this thread but happened to bump into it. Recently managed to get my hands on quite a few Champions sourcebooks (notably Champions Universe, Beyond, the 3 Villains, Book of the Destroyer, Book of the Empress, Mystic World and a few more) and I've been loving them. Really cool setting (that I first bumped into in Champions Online).
What books were planned for the setting? And where can one find the mentioned publication schedules?
