Two rods are covered, the Rod of Stolen Starlight and the Rod of Silver Rain.
Also there is official confirmation that there will be equipment for Artificers and Invokers (and by extension the rest of the PHB2 classes) in the preamble for the article.
I just realized there was a bit of information from a preview I missed today, in the Mini's preview. Normally I wasn't covering them because we knew all about the minis in the set, but today also had "You'll be able to find monster statistics for all the draconians in the upcoming Draconomicon: Metallic Dragons book."
Does that point to, or away from the next setting being Dragonlance? You decide, or wait until the announcement at GEN-CON.
