Though the sci-fi action-RPG later appeared on PC, the title is still considered an Xbox 360 exclusive in terms of the console market--meaning it has not appeared on rival systems PlayStation 3 or Wii.
Speaking on Mass Effect 2, BioWare senior manager Matt Atwood previously expressed his belief that the sequel would "be Xbox 360 exclusive for at least a short period of time," followed by a PC release "as quickly as possible."
Following EA's $860 million purchase of BioWare and Pandemic, many speculated that the PlayStation 3 would receive a Mass Effect game, especially given BioWare's plans to deliver at least three Mass Effect titles and the tendency of EA-published titles to hit both Xbox 360 and PlayStation 3.
Dragon Age, another one of the company's in-development titles, was originally slated to be a PC exclusive, though the company recently noted that the franchise will eventually hit consoles as well.
I imagine my PC will be upgraded to play Mass Effect by the time it rolls around to PS3, but still, nice to know I might be able to give 'er a shot if not.
