Back in June, BioWare hinted they would be revealing Mass Effect DLC news, in the same week this statement was made.  However, we never got any announcement for it.

Turns out that big news was delayed, and we are just now hearing more about it.  Three new Achievements have been revealed for the "Pinnacle Station" DLC, a name which we learned in winter belonged to a gambling establishment -- likely illegal too.  It's apparently like a fight club, and players will get to participate in various combat scenarios.

The Achievement cap has been raised to 1200, and the three shown recently are 50 points each.

• Undisputed (50 G)
  Complete Ahern's survival mission
  
• New Sheriff in Town (50 G)
  Take first place in any combat scenario on Pinnacle Station
   
• Best of the Best 50 (50 G)
  Take first place in 12 combat scenarios on Pinnacle Station
