This is great news. Hopefully this opens the floodgates towards emulation and homebrew. Not that there are really any exclusives, but it would be interesting.

Xbox One homebrew has effectively always been supported. Anyone can register a development account and boot the system into dev mode. IIRC in a talk about console security, a Microsoft developer noted that this was an intentional deterrent against hacking. An effort to split the community so that pirates and homebrew enthusiasts wouldn't have a reason to collaborate.

Seems unlikely. Someone would have to turn this into a modchip, set up physical distribution networks (all very illegal under the DMCA), and it'd only work on the 2013 machines - Chen's team clearly anticipated this type of attack and were already working on mitigations around the time the Phat released. So as he says at the end, later silicon already has more glitch mitigations built in and has done for a long time. Current gen Xbox isn't even investigated but we can assume it's even harder. They were clearly paying for red teaming. Remember: ZERO software bugs in the boot rom.

Very few exclusives. Couple of Forzas? Halo 5? Practically everything else available elsewhere in similar quality.

I'm just excited at the opportunity to re-purpose my old launch day XBone as some kind of little homelab linux box.
