Yes but Bethesda already knows the story, and has already made the story for the next game around it. What he was saying that the book's actual release doesn't effect when they'll announce the game.
Ah, well he did not quite clarify that AND that part was already said. I understand my quote was unnecessary.
Actually he might be wrong though. Bethesda might want to wait until the book is done to announce the game. Lets not forget how long it takes to publish and distribute. I am not going to state reasons because everyone else has already given my opinion.
