Where does that 2:1ratio come from? I thought XBS was selling much closer to PS5.
Yup, but I believe some fair assumptions is that during the announcement of the game back in 2019, before next gen was released, and Larian has been entirely non-committed to any platform but PC during the Early access days. They largely back then seen the landscape of things from 2019 POV.
It was announced for State of Play just a few days ago before all this came to light, which means in order to be on state of play, and to announce for PS5, there must have been a point in time in which there was a commitment to deliver it for the platform. Sometime between 2019 to well before 2023, as it releases this August, the PS5 version has been in full swing development.
The Xbox version still has not been announced in an official manner, which suggests that the platform still remains uncommitted to release despite what the tweets imply here. If Xbox is not announced as a platform from now to release date, and if BG3 craters upon release in August, there may be no xbox variant released if they choose to push resources elsewhere - it is one of the advantages of being non-committed to release. You can change plans if necessary without any public facing backlash.
I'm not seeing this as a technical challenge here, at least, not in the sense that they are wrestling hardware down as we are suggesting here. IMO, they just don't have the resources to release the game on PC and PS5 and Xbox simultaneously in a fashion in which all three versions would be polished. The last time Larian made an announcement for DOS2; it was April of 2018 releasing for August of 2018 for both platforms, a full year after PC was released.
But I think Sony wanted to move their own release date up to release in conjunction with PC. Thus we are in the situation we are in today. If history is to be repeated, I suspect BG3 was not slated for consoles until next year August. Sony moved things up, and there's just not enough there for them to just push the Xbox platform to release as well.
And the reason I think Sony moved things up - well it's in the state of play.
From wikipedia:

You can see a pattern of staggering releases here. Same Larian engine for BG3.
