Has that actually been stated? The most I ever heard was an asari talking about how "no one remembers what a quarian looks like any more".
Last DLC for ME2, dubbed Arrival, releasing in a week. A little surprised. I figured they'd wait until closer to ME3's release date.
It's worth it for no other reason than you can retrain your squad members' powers once you complete the mission.
Arrival was certainly short and sweet, only about 2 hours long, which for $7 might seem to be a bit much. Of course, you’ll spend that much on a movie nowadays. Not quite as good as Lair of the Shadow Broker or Overlord, in my opinion, but it does have a unique style, and the outcome has some interesting implications. Bring on ME3.
