Despite its comfortable new digs at Electronic Arts, it looks like BioWare plans to keep its Mass Effect trilogy exclusive to Xbox 360 - for at least the time being.

"I believe we’ll be Xbox 360 exclusive for at least a short period of time," BioWare senior manager Matt Atwood revealed to CVG on the subject of the sequel’s release plans.

"We’re still working out the details on that, but we’ve had a great relationship with Microsoft and done very well."

It had been speculated that following the Electronic Arts buyout, the Microsoft-published RPG would take a multi-platform route with its two announced sequels.

Atwood’s words seem to be the first indication that Microsoft isn’t yet willing to let its front-running action-RPG drift to the competition (if, indeed, it has handed over cash for the sequel).

And after the exclusivity deal ends on 360, it looks like it’s (expectedly) onward to PC for Mass Effect 2: "I think you’ll see a PC version not too far away," said Atwood, confirming that the sequel will also be making its way to mouse and keyboard users.

"We haven’t solidified the plans yet but we’re headed in the direction where we want to be as close as possible [on PC]," he said.

So far we don’t know much about the second Mass Effect, though BioWare boss Greg Zeschuk shared a few words with MTV:

"We look at Mass Effect 2 as incredibly exciting," he said. "Just the amount of effort and knowledge and know-how that went into building the technology for the first one is huge, and [we now have] the chance to actually make things a little bit richer."

After having cleared the ’Bring Down the Sky’ DLC this week, we’re gagging for more.
