Fail? No. The Xbox One will sell a ridiculous amount of units. As much as the PS4? Probably not at launch. The Xbox is a household name, far more than the PS4 is, and there is a very large target audience for it.
Both consoles are going to sell well and both consoles are going to succeed. One will succeed more than the other, and that's to be determined in the years to come, but it neither will "fail".
