This prediction would have an ounce of possibility if it was a company like Sega against Nintendo, but as it stands, Microsoft is way too rich as a company to let such outcome be in the realm of possibility.
In fact, Microsoft can afford to beat Sony by cutting Xbox One to $300 tomorrow, but that's not going to happen because it doesn't make too much economical sense, and shareholders wouldn't be too pleased with such decision, however, my point is Microsoft can afford to be way more aggressive in selling Xbox One compared to Nintendo.
Edit: I see no point in you reiterating yourself as you have already made a similar topic.
