Xone won't fall that low for many a year.
It has 3rd party support just through having parity with the PS4, that alone should ensure it won't drop that low and even if it got close to that I'm sure MS would drop the price like they did with the OG XBox and Nintendo did with the 3DS.
If Wii U does it'll be before MK8 drops after that it should be able to float above 20k for 2014 at least.
