I think people are turning launch into a way bigger drama than it really is. These machines are intended to last for 6-7 years, as long as there's some fun stuff to play at launch and cool shit announced for later on who really cares about launch?.
A year or two from now no one will give a shit about all of this, same as how in 2015 no one gave a shit that the PS4 and Xb1 had a terrible first year. We were hyped to play the Witcher 3 and Bloodborne and Halo 5 and Arkham Knight and MGSV, etc.
Xbox is focusing on backwards compatibility because due to bad luck, or COVID , or incompetence (or something else...or all of them) they don't have much else at launch. Right now it's also the topic of the week because the embargo on these machines just got lifted and we are finally getting details we have been wondering about for months. Why wouldn't it be what everyone is talking right now when we just got a big info dump about all of this?
It's not like backwards compatibility is everything we have been talking about for months. There's been plenty of talk about new games, new tech, new engines ,etc.
Anyway, ease up, It's just a console launch.
Give it some months or hell, even a year. When Horizon 2, Halo Infinite, God of War Ragnarok, Avowed, Elden Ring, Tales of Arise, That Harry Potter Game, Final Fantasy XVI, RE8, etc are either out or closer I can guarantee you the main topic of conversation isn't going to be how The Division 2 runs in backwards compatibility mode.
