You can be sure that 7 mill (and counting) PS4 sold in Japan is more profitable than 10.5 mill PS3.
Usually, you guys fall over each other to point out how big of a failure PS3 was financially. You can't have it both ways.
Ps4 has a few million ps plus members in Japan paying 60$ a year. Sony get 30% cut on all digital sales including microtransactions. Ps4 hardware is so long due a big price cut they must be making a pretty penny per console. I just can't see when all is said and done the 10 to 11m ps4's don't make Sony the most profit in a gen ever.
