No Tomb Raider Demo Before Launch

No playable sample for Tomb Raider reboot prior to March 5
Karl Stewart, Global Brand Director at Crystal Dynamics, announced via Twitter that "there are no plans to release a demo of Tomb Raider pre-launch". The reason? They don't want to spoil the story.
Tomb Raider is expected to be available on March 5th, for PC, PS3, and Xbox 360.
