You mean he knows how much additional engineering time and money is usually needed for develping a game on multiple console performance targets, and how that can affect the strict budgeting and scheduling for launching a game?
I thought the opinion from devs on Lockhart was pretty much a known variable at this point. During last year's E3 the folks at DF were pretty clear about that IIRC.
The SeriesS definitely won't run OneX games, not because it has lower bandwidth (RDNA2 is more effective than Polaris at using bandwidth), but because it's lacking 2GB of RAM.
It's just not possible for the SeriesS to run OneX code.
Maybe Microsoft had originally planned to put 2x 2GB + 2x 4GB modules (12GB total) on the SeriesS, but eventually they realized the 4TFLOPs RDNA2 wouldn't be able to reach the 6TFLOPs Polaris at all times.
I agree. No all-digital console ever got any migration system from physical copies. The PSP Go didn't, the XboneS All Digital didn't and I'm pretty sure the discless PS5 won't either.
Maybe this will mean a handheld is coming when fabs reach 3nm or 5nm.
