UPDATE: Respawn has announced the official release date for the game, you can find all the details here.
ORIGINAL: Respawn Entertainment has released a new screenshot for Titanfall alongside the promise of a “special announcement” later today.
The screenshot is accompanied by the message, “Be the First to Fall into Titanfall,” which seems to suggest that the announcement will be about the game’s beta. Titanfall is set to release in 2014 for Xbox One and PC.
