As you may or may not know, the Dragonlance Campaign Setting (i.e. the "core book") is being written by Sovereign Press but is being developed, edited, and published by Wizards of the Coast. The FR book set the standard in how WotC campaign worlds are presented, and yes, we do have copies in our office to reference. The outline we originally created was done to match the structure and flow of information found in the impressive FR book.
That said, our book will capture the feel of Dragonlance, and while still full of the "crunchy bits" many gamers love, we are also including lots of world information, flavor, legends, mythology--all of the elements that make Krynn what it is. I believe it will appeal to both min-maxing hack 'n slashers (dual-wielding minotaur barbarians!) and those who love the novels.
