Well, it's pretty obvious that PS5 is beating the XB2. I think it and the Anaconda will be pretty much the same power level. Nothing like the 40% the PS4 had over the XBO. Probably more like 10%-15%, if one is more powerful. And in that scenario Sony wins. It's possible it will be close in NA, but in Europe and Japan it won't be close at all.
Of course, there is a chance that the more powerful box is the Xbox 2, but if that's the case I see Microsoft not wanting to take much of a loss or any loss at all. So it may be a little more powerful, but it may also be $50-$100 more expensive. That will help PS5 even more.
