To achieve that lofty goal, Microsoft will have to ensure a sales average of 1.25 million per quarter for half a decade. How does it plan to do that? Mehdi notes that a large number of those sales will "probably come from replacements," but Microsoft is also planning a "huge announcement" related to the Xbox 360 for E3 to reinvigorate the aging console. We recently confirmed that a dashboard refresh is coming to the console in the next few months. Although we haven't heard any details other than to expect a "visual refresh," it's likely that Microsoft will update the interface look more like the new Xbox One UI, just as it did for older smartphones when transitioning from Windows Phone 7 to Windows Phone 8. It's also possible that Microsoft could be planning on refreshing its console, or reworking the subsidized pricing strategy it introduced last year.

I won't be surprised if these fukking idiots will release an "upgraded" version of 360 which games won't be compatible with the old one.
