Why can't you respect the fact that we don't want this thread littered with unconfirmed rumors?
LOL
like all the posts about game x being exlusive?
anyway.
with the rumoured (due to MS not revealing specs) lower "power" of the Xbox One I would not be surprised if MS has planned shorter life cycles for the hardware. Especially if they want to compete with future Apple TV-boxes rather than the PS4. The Xbox One brand will continue but they might upgrade the hardware every two or three years. If they plan on selling the Xbox One subsidized to most people this might be a viable path. People just get a new subsidized box when they want to renew their subscriptions. Though this will be, again, very US (maybe UK) centric.
