BioWare has a post on BSN breaking down the From Ashes DLC.


 * From Ashes includes the Prothean squadmate, a mission on Eden Prime, a new weapon, and alternate outfits for all squadmates.
 * This is the bonus character and mission DLC in the CE.
 * According to BioWare, From Ashes was developed separately from ME3 and wasn't completed until after ME3 went into certification. The content in From Ashes is optional.

BioWare plans to release some official screenshots and video of From Ashes soon.
