Despite the first Mass Effect being billed as an Xbox 360 exclusive, famed developer BioWare tells Joystiq that it has "never confirmed any plans of Mass Effect exclusivity for the trilogy."

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.

The upcoming sequel to BioWare's sci-fi RPG Mass Effect will arrive on Xbox 360 first with a PC version hitting soon after, according to senior manager Matt Atwood.

"I believe we'll be Xbox 360 exclusive for at least a short period of time," Atwood told CVG. "We've got a really great PC fan base, we think it's really important to deliver the PC experience as quickly as possible," he continued in a VideoGamer interview.

The first entry in BioWare's planned Mass Effect trilogy arrived on Xbox 360 last fall, with a PC version, co-developed by Demiurge, due out May 6. Many had speculated that, following EA's acquisition of BioWare and the publishing rights for Mass Effect, the sequel would release simultaneously on multiple platforms.

BioWare has yet to specify a release window for Mass Effect 2.
