the problem is not the price, is the value of the system.
do you remenber what happened with ps3 and 360?
while microsoft only has third party games, ps3 had third party games as 360, more exclusive third party games and more first party games like: god of war ascension, sly 4, the last of us, puppeteer, beyond two souls, rain, etc...
when you buy a playstation, you spend your money thinking in the future. xbox console is buy a system with closed eyes.
this an example of games:
first party exclusive games we know to release 2015: bloodborne, the order 1886, ratchet and clank reboot, tearaway, until dawn, uncharted 4.
third party exclusive games for ps4 we know to release 2015: guilty gear Xrd, persona 5, dragon quest heroes, Rime, no man´s sky, akiba´s trip, one piece, ultra street fighter 4, street fighter 5, deception IV, final fantasy X/X-2 HD, jojo´s bizarre, drawn to earth, samurai warriors 4, etc..
how can do microsoft to beat all that?
