After supposedly stating in an interview that the Mass Effect trilogy would be exclusive to the Xbox 360, BioWare reps claim that CEO Dr. Ray Muzyka, in fact, never uttered those words.
The story broke on the Internet via the website XboxOz360, which claimed their source to be the magazine Australian 360. The quote directly from the magazine is as follows:
“Speaking exclusively to 360 at EA’s European Showcase, BioWare CEO Ray Muzyka restated his company’s commitment to bring the Mass Effect trilogy exclusively to the Xbox 360, despite having been brought up by Electronic Arts and analysts claiming it would go multiplatform.”
So, as you can clearly see, Australian 360 printed the word “exclusively” in their magazine. This apparently must have been a misunderstanding on their part, as BioWare reps claim Dr. Ray “never confirmed any plans of Mass Effect exclusivity for the trilogy,” and that the “site is incorrect”.
So while this doesn’t necessarily rule out the Mass Effect trilogy as being exclusive, it certainly has confirmed that nothing has yet been confirmed.
