100% MS. Nintendo just launched a console that has still maintained high demand 3 months later. Sure, this may not last, but seeing that the Switch is seeing all of Nintendo's focus, and therefore all of their 1st party titles, I definitely don't see it performing poorly by any stretch of the imagination. Nintendo's first party titles always push their HHs to higher sales. So, I think sales around 3DS's, at this point, seems pretty realistic.
MS, on the other hand, just seems redundant in the console market. There is already a company that is doing what they do, offering core home console gaming, only better. Sony also has many more exclusives that are more varied. And the XBX isn't going to change this.
For one, $499 has never been a good price for a console. No console at that price has found mainstream success. MS had to quickly drop the XBO to $399, and then $50 less than the PS4, to even compete. Luckily for Sony last gen, the PS brand was large enough to overcome it. Though, I doubt they could twice. Two, the XBX is only going to appeal to a handful of markets. Namely, US, UK, and AU. Everywhere else, the XBO, and therefore the XBX, is basically dead. And finally, without any exclusives, fewer people are going to be interested in it. MS doesn't really seem to care about mending the XBox brand, which a $399 XBX and 3-4 big exclusives announced at E3 would have gone a long way to doing. They seem more interested in making money off of it while its still around.
