I just wish there had been something in there for wizards? Is that next?
I picked up the toolkit/expansion... Very cool!
FFG have release a cryptic "what's coming" document here:

The next expansion is the campaign set, but it is generally agreed by most forumites that the whole "wheel" vision is something to do with a magic supplement
You can see the full discussion on the cryptic teaser here:
