For me it's not so much about brand loyalty, although I like Sony more, I won't buy either of these machines (at all, I guess, certailny not in the forseeable future). It's just that the XB1 as a product fails so hard and is such a rip-off that I just can't get my mind behind someone who is buying that thing. But that's just my personal issue, I guess.
Although all people around me who are buying that thing are just fanboys in the sense of "new xbox, I'm buying it anyway". They even know about the shortcomings, they just don't bother. It's not great for the industry, just to think about that games are still made with a 1,18TFLOP machine in the mind the next coming years...that's shit. Hopefully it doesn't sell great so that the impact stays minimal.
