Pre-order materials for Bungie's Destiny leak

Bungie is set to unveil its "next universe" in a "matter of days." In fact, the game will be revealed this Sunday at 10AM PT. Pre-orders for the game will be available shortly afterwards, as retailers have already begun to receive promotional material for the game.

Joystiq got its hands on a double-sided poster that will supposedly be offered as a pre-order bonus from GameStop. According to the site, pre-orders will begin on Monday. More promotional materials can be perused on Twitter (via NeoGAF).

Tune into Shacknews on Sunday, as we'll have much more to share.
