Examiner writes: Included on the announcement page was five screenshots (click here to view). Just from those pics you can see what is possibly a new (or designed slightly different) mech, as well as what possibly looks to be the ability to play as a Marauder.
What did not come from the the official pages, is the words from an employee who confirms there will be achievements (and trophies if you are playing on a PS3). They are making sure this content will be well worth it, kudos to Volition/THQ for putting out a great game and supporting it. We better see it hit the top of the Xbox Live Activity charts when that DLC hits.
