In the September issue of Australian 360, BioWare co-founder and CEO Ray Muzyka was discussing the future of Mass Effect and the possibility of multi-platform at the EA European Showcase. "We said we were committed to supporting Mass Effect as a franchise and have the trilogy on the Xbox 360, and that's still our goal", Muzyka told the magazine, later adding "we're always very ambitious in our goals and the most important thing is quality, so we're never going to compromise that."
The quote doesn't actually lead us to believe that the series will be exclusive because the word is never actually uttered. If anything it provides the insight that the series will always be on the Xbox 360 but Muzyka never says it will only land on Microsoft's console. As one reader points out, it's more of a nod to the entire trilogy making it out this generation.
Questions regarding the fate of Mass Effect have been in the air since Electronic Arts acquired the famed Canadian developer -- who hold the rights to the Mass Effect name and universe. With major companies going multi-platform to make up for costly development we'd be surprised if EA went this route. Unless of course a deal is in place that was made prior to the EA acquisition or shortly thereafter.
