Making the HD-DVD an external add-on for the Xbox 360 was a smart move because if the world decides that Blu-Ray is better, then, Microsoft can go ahead and release a Blu-Ray drive.
According to Peter Moore. In an interview with Japanese website ITmedia, Moore noted that, if the format war concluded with Blu-Ray as the clear winner, Microsoft could release an external Blu-Ray drive for its 360.
Some people are a little surprised as Blu-Ray is backed by their rival: Sony. But it would not be smart marketing on Microsoft’s side if they did not go with the flow by supporting a dead technology.
Moore again stressed that the external drives would be for movies only, but something tells us that external drive could become vital for gaming two or three years into the console’s lifespan.
