This just in folks. According to Christina Norman, lead game play designer of Mass Effect 2 there will be no GOTY edition of ME2.
Q: Is there any chance of a Mass Effect 2 Game of the Year edition with all the DLC?
Closest thing is ME2 PS3
So there you have it. If you were waiting for some fancy edition with all the previously available DLC and maybe some extra goodies, you’re sadly out of luck.
