So far it's just Kotaku and Polygon reporting this, right? Or did other sources back up these leaks too?
Brad Sams
Although Sam's stuff does not appear to be originating from the same leaks as Kotaku and Polygon. Those two got their info from devs that met with MS last week at a meeting to discuss Scorpio. Sams' info seems to stem from somewhere else since he had info on the two smaller devices that MS is going to announce at E3 and not much on Scorpio, though he had heard about that too.
