If people have wondered how much a PS4 Dev kit costs. It is 2500$ but the best part is that many many Indy developer are getting Devkits for free.
Although this $2,500 price is being cited in development circles, the game-makers we spoke to all said that Sony had lent them dev kits for a limited period of one year, for free. As of right now, there are no dev kits being sold. Sony is sending whatever it has available to favored developers. "All the indies I know got them for free," said one developer. "Sony has been amazing about kits and development thus far."
Also think about the fact that these Devkits have no restrictions whatsoever while the "Cheap" and not "real" Xbox One dev kit has a lot of restrictions and they need to pay MS a not told fee as well.
