Yeah Polygon's information doesn't feel as reliable as everyone else's.Aside from the announcement timing I could see this being true actually, but this whole slew of leaks we got today just paint a weird picture to me. 3 new Xbox SKUs in the next 1 1/2 years? As well as apparently full integration with Windows 10 of everything Xbox? An Xbox One that's 4 times as powerful as the current console? How is that worth it, if you still have to support the original Xbox One? I guess they are going full on Steambox with Xbox, but what's the point of having Xbox consoles then in the first place?
Though I can kinda see why this rumour is escaping some of the same criticism the PS4k has gotten at the moment, the PS4 already is the strongest console on the market, so owners don't feel like they needed anything stronger. The X1 is weaker than the PS4 and we're constantly reminded of that, so maybe core Xbox fans are more open to a stronger Xbox One to get away from that stigma of having the weaker console.
