We keep seeing the same numbers come up again and again from different sources.
Sure, it might all be guess work, but it's suspiciously consistent guesswork.
I'm still thinking the delay in announcing prices and the XSS is all down to how cheap Sony are willing to go on the Digital PS5.
If there's no XSS, Sony don't need to discount as heavily.
If the PS5 Digital is no cheaper than the disc version, then MS potentially don't need the XSS at all, and can avoid the inevitable bad press from graphics comparisons, or eventual customer dissatisfaction at the idea the XSS is holding back next gen games.
