X1 will get outsold regardless so it doesn't really matter
A 360 that was 100 dollars cheaper, had a year head start, 1 full year worth a retail releases already set in its library, a flood more of xbl games, superior online and better multiplats was still getting outsold by PS3
A 350 Xbox One without those advantages will also get outsold by a 400 PS4
They will be getting outsold regardless of the price
