Microsoft has strenuously denied there being any connection at all between the development of the Xbox 360 Slim and the PS3 Slim, saying the new Xbox was in development long before Sony announced the revision.
When asked about the matter, one of Microsoft’s top marketing bosses had this to say:
“I think the decision to do this was made before their announcements last year. It’s part of the natural generation of a console to refine the components and make it sleeker and quieter and all that.
I wouldn’t say it was directly related [to PS3 Slim].”
Oddly, something very similar was said about price cuts mysteriously coinciding with the release of the PS3 Slim, and so far the only company to be routinely releasing slimmed down versions of its consoles is Sony.
