The PS4 will easily win the United States

Yes. PS4 will be 300 dollars in 2015 and 200 dollars in 2016.

1) Selling more SW due to larger userbase and worldwide penetration
+
2) Continuous increase in PS+, PSNow and PS Vue(once it starts) revenue. [The rebranding of music and movies will also likely increase revenue in that field, with Ps Music doing better than Music unlimited (for comparison's sake, Unlimited was not available in almost every country, while PS Music has been confirmed for most national markets)]

= no need to profit from HW.

Sony's strategy has been to a) increase user base and b) increase average revenue per user. A) is happening nicely and b) should happen this year (might have already started).

The Xbox division can only respond with cuts to 250 and 150, respectively. But that'll just keep it closer to PS4, it won't make it #1, as being 50 dollars cheaper does not seem to be enough. Taking losses in HW + low revenue in international markets = a lot of bleeding. They are lucky to be under MS's wing, and therefore their coffers, or such a situation would signal the end of the brand. But it won't. But on that subject, speculating about next gen is something we shouldn't do yet due to uncertainties about the direction the industry will take (yes, the cloud "problem").

TL;DR: With Sony raking in revenue from the worldwide playstation userbase on several fronts, and production costs lower than the competitor, they'll have no difficulty dropping the price. Both cuts I mentioned above will not happen during holidays, they'll happen in the middle of the year (May-September) to avoid stock shortages.
X1 will take some NPDs each year, but the overal yearly sales will always favor PS4.
