The Writer Returns

I hope everyone is prepared to jump back into the twisted nightmare world of Alan Wake, as the second and final piece of DLC (named The Writer) will be available in about 2 weeks. Hitting the marketplace on October 12th, The Writer promises to give us answers to the questions remaining from the main game. My only question now is, can we expect it to answer ALL questions, or will a few be left unanswered to keep us guessing until Alan Wake 2 comes out?
