imo, xbone sales have slowed noticeably enough that MS is getting worried, and they feel it's time to 'leak' numerous infoes on xbone's bright (white!) future.
smart move. Sure, they could hold a press event, by why? Word will spread just as fast this way, too.
Well the benefit of having stuff "leaked" is that you can gauge how the community reacts to the news and act accordingly. If you make an announcement you can't take it back but a leak is not confirmed or denied
Quantum Break is definitely not coming out this year.
I'm surprised MS would bank on Sunset Overdrive that much. I love Insomniac as a company, but their track record on PS3 ranged from pretty good to downright bad.
Yeah they're hit or miss. Plus the art style of Sunset Overdrive is ugly IMO. Still though MS has a lot lined up the first year if the rumors are true
