Story far too "personal" to be spoiled.
Apparently discounting all the footage and information already released about the new 'Tomb Raider,' including no shortage of controversy and delay, Karl Stewart, Global Brand Director for Crystal Dynamics announced today via Twitter, "For all those @tombraider fans asking. There are no plans to release a demo of the game pre-launch. We don't want to spoil the story........"
According to Destructoid, Karl later expounded on this story concern, "We've weaved such an personal story we don't believe spoiling it by having you wait a week or so to play on, delivers on our promise."
Responding to the notion that the entire story has already been revealed, Stewart quipped, "you've seen nothing yet.....trust me!!"
The possibility of a demo for the game post-launch remains, likely at a time where the entire story has been revealed through video and print throughout the internet.
