Gamble didnt go into detail about any planned future for series beyond Mass Effect 3, but he did say this about Commander Shepards send-off.
"We want the outcomes to be satisfying to the player. That doesn't necessarily mean they're all going to be happy or positive, but they have to be satisfying. Players have to understand that the choices they've been making in this game and in previous have had an impact, and that they're an architect in what happens."
BioWare has also launched a new Facebook app called Mass Effect 3 Mission Command, which will allow fans to unlock in-game items and avatar items and DLC.
Mass Effect 3 is scheduled to launch on March 6th with a demo slated for release on the Xbox 360 later this month.
