EA has announced that Mass Effect 3 will be releasing on the PlayStation 3, Xbox 360 and PC, all on the same day. This is a far cry from the series' foundations.
The original Mass Effect was an Xbox 360 exclusive and it saw a PC release around 6 months down the line. Mass Effect 2 saw a same-day release for the Xbox 360 and PC.
No specific release date has been offered so far, but the VGA teaser trailer stated that it would arrive during "Holiday 2011".
