As a Nikon user, I find the Nikon Rumors web site of inter­est. They search the world adver­tise­ments for hints about new and dis­con­tin­ued prod­ucts. If you are in the mar­ket for new equip­ment, check out the Price Watch page for known best prices and sug­ges­tions for whether to buy or wait on evi­dence that new prod­ucts are about to be intro­duced.
