I long for the days when we gamers didn't need to care about these things.

Hopefully not that much.

Depends from currency to currency.

I don't think MS is taking a loss on Xone. but sony is certainly taking a good loss with ps4, maybe a little over $50.

MS is probably losing alot, Kinect 2 is rumored to cost about the same (if not more) than the actual Xbox One. Rumor has it they are making a big loss even on $500

No more than $20, I don't think the loss will be high at all.

Sony is making a small profit on the PS4 and Microsoft is probably losing a lot on the X1 because there are rumors that the kinect cost just as much as the console, even if that is not completely true it is still costing them a lot to make.

Indeed.

Sony arent making a profit because of the changing exchange rate of USD and Yen unfourtunately. but that loss wont be crazy big

This a sales site, of course there is going to be discussion over these types of things.

Sony will make a small loss on the system, probably around 30-50$. I think Microsoft will at least break even, I doubt the Kinect costs 100$ to make.
