Err.. Windows10 is required? What another typical load of crap from MS... like DX10 "required" Vista in order to get PC gamers to ditch WindowsXP - we saw how well that worked!
That's pretty much okay, who really buys the Xbone anyway? The PS4 is better in every way, it has more exclusives (other than the Halo series and a few other MS titles). Sony is already shipping out the REV2 type boards which are much smaller than the original PS4 systemboard. Its cooler, its cheaper, its higher-tech, faster system in a package that is almost half the size without looking like a POS 80's VCR. So, Sony still sells the PS4 for about $50 over the Xbone and its worth every penny.
