Da Vinci Code, the game

Over at Adventure Gamers they have this piece about the announcement of the game based on the film based on the book. I'm not quite sure how they're going to create an action based game without straying from the strengths of the book. Surely a fairly straight adventure would have been better? Perhaps as we already have Broken Sword and Gabriel Knight, a Da Vinci Code adventure might have been too similar. :)
