Since people keep throwing around Cyberpunk day one for Game Pass, I have to wonder what the point would be if it's still just the current-gen Xbox One version, and this is meant to hype people up for the next-gen launch.
I feel like marketing-wise, it makes more sense to try and push for the next-gen version of Cyberpunk earlier on Xbox, while having marketing and gameplay demos showcasing it early as this year.
Cyberpunk is a game that's going to look noticeably held back by the current-gen, so if you can have a version looking (and likely playing) a lot better, exclusive to Xbox for some time, while also showcasing how next-gen can look/play, that'd make a lot more sense to me.
That'll combine with the fact that people can still buy the current-gen version this November, then get the free upgrade possibly a few short months later. An immediate display on the benefits of Smart Delivery.
