Thinking about it,
Sony has nowhere to run this time.
Microsoft has employed a strategy of building bigger than Sony in everything now. Sony can't possibly manage a tie like they did with PS5 (due to MSFT misconfiguring). Sony likely can't even possibly come close lol.
PS6B: 52CU, 96ROPS, 10MB L2, 640 GB/s, 160W
XSX2: 68CU, 128ROPS, 24MB L2, 768 GB/s, 275W
XSX2 will beat PS6 by 50% clean. The gap is literally 4070S vs 5080. And since it's a PC, Microsoft has much more freedom to configure 18/24/36GB VRAM Magnus SKUs that will undercut the PS6's 30GB.
If XSX2 is a PC, with the ability to use Steam + Xbox Libraries and free online. Even at 749$ vs 1199$, I would say that the PS6 is doomed.
The more interesting one is the PS6 Handheld. Half PS5 Performance but in a much more attractive form factor. Especially since it will double Switch2's performance.
