We know about the Xone, so what will the PS4 cost?

[Train wreck]

the ps4 price is not even the main point. Microsoft introduced a new model 360 and kept the price the same (with its kinect integration), Sony can easily come out with a PS3 slim with a $179-199 price and undercut the 360 (and Wii U) and have its new PS4 at $399-449.
