Well let's see.
The CPU is the same.
The GPU is very close and likely to not be any difference in cost when you consider the embedded ram on nxbox.
The ram is probably 1/3 of the cost or 1/4 as its DDR3 vs GDDR5, so there is savings there.
Everything else is primarily the same. Both will have Bluray, HDD, PSU, wireless-n, ethernet, usb3.0, and other casing requirements.
So consoles will be really close in cost.
MS will likely have a far lower priced controller as they won't be including a touchpad or motion tracking of any sort. Probably just a different ergonomic style.
So at this point you have PS4 having a higher cost than nxbox. But now you add in their respective camera systems.
PS4 simply has a dual camera. It is better cameras that previous pseye and of course two of them. That's about it. It won't have all the other tech to be as finite in 3D space as Kinect2. So Kinect2 will have a significant cost above the new PSEye.
Once you add that into the mix its very easy to assume nxbox will definitely cost more in raw components than PS4. However, that doesn't mean the retail price won't be identical or so close it won't matter and only come down to bundled games and other offers.
I say both will launch $400 to $500. Pretty much what I've figured for years now. I only dropped as low as $350 due to rumors over the last six months, but I think its safe to say it won't be below $400 unless it comes with some kind of contract and/or loses the packaged in camera systems.
