In my post The Forgotten Realms in 4th Edition, Part I, I wondered if Drizzt's inevitable new novel would respect the one hundred year time jump that the Forgotten Realms would be undergoing in 4th Edition. What I didn't realize is that apparently it already has!
R.A. Salvatore's most recent Drizzt's novel, The Orc King, has a prologue and epilogue set one hundred years after the primary events of the novel. The Spellplague is mentioned by name, so it is officially tied in to 4th Edition. Heck, it is even labeled as "Forgotten Realms: Transitions, Book 1".
