I really value the insiders here and feel like we've been pretty well informed on everything coming up for a year and a half. But the only thing that hasn't made a ton of sense is the insistence on what is a console, and what is a PC. I'm not going to worry about it because I suspect it's mostly going to come down to semantics.
If you want to get a box that plays Xbox BC games, and has access to all the PC stores, you will be able to. If you're into Xbox currently it's going to be a massive W on every single level but the hardware price up front. You'll get what you have now, plus every other game in existence for the most part through GoG and Steam. EPIC free games. Gamepass access, all of it. Just pricy hardware.
I think every game for either the Xbox "console" or the Xbox PC store will just be a PC version, period. Again, semantics. No one is expecting these systems to sell a lot. No developers are going to go out of their way to make specialized versions for Xbox "console." Every game comes to PC now, and that's what we'll get. MS may have a quality control process for checking updates or whatever, but it will likely be on them.
As for the debate about Xbox BC stuff on PC, the AMD video is pretty clear. Unusually clear. Unprecedented BC, and coming to a range of devices. So if insiders are not seeing that now, I would expect that eventually we could see laptops, handhelds, and PCs that might incorporate a chip for BC. I guess we'll see. If not, get the "console" which is going to be a PC anyway.
