At $350, it would match sales. At $300, it would win NA and UK by a landslide.
Even at 300 it really wouldnt, it would eak out a win (55%ish) but no landslide ever.
Lack other advantages for a landslide, just look at what it took for 360 to do it.
360 handidly won the US for a while, and has still sold more units in NA and UK than the PS3. If MS cut the One's price by $200, I could see it selling 50% more than the PS4 in NA, easily.
Alot of people saw X1 winning March ndp and PS4 sales dropping after xmas, then Jan then feb then march and so on and so on. There would be nothing easy about it, just casue you seedoes not make anything about the outcome at all realistic.
360 had a few other thing go right for it X1 does not even if they fixed the price issue and had a sku going for 299.99
PS3 was over priced as fuck, PS4 is not
360 had the better 3rd party games, now its reversed.
360 had more games, now its reversed.
360 was easy to dev on PS3 was a bitch, even this has reversed this gen.
360 had a years head start, X1 does not.
And the biggest was Sony own giant early fuck up, something revresed this gen.
