In response to Sony's criticisms of the Xbox 360, Microsoft calls Sony both "complacent" and "out of touch," while noting that the PS3 would have to first catch up to the Xbox 360 in order to outsell it, something they claim they "can't imagine."
Xbox 360's product management director Aaron Greenberg told The Bitbag, "I can't imagine any scenario where the PS3 can catch up with us."
Greenberg also says that "this sounds like an old hardware company that's comfortable with its market position. That complacent attitude is out of touch with where the industry and consumer is today." Later on in the message to The Bitbag he says "I can't imagine any scenario where the PS3 can catch up with us. In fact, even if you doubled the current PS3 sales and Xbox 360 remained flat, they couldn't close the gap until 2014."
