There's still loads of speculation surrounding a release date.
Just in the last few days I've seen everything from 4th September to Jan2012....... The only thing anyone can say is "we'll know when we know".
The only release I'll believe is the one that Bioware give me. And as of this moment in time, they havent given me one
My own personal speculation would be Oct/Nov 2011, but I have absolutely no evidence or data to back this up.....
