To put it bluntly, XS at its current state is almost a nonfactor unless Series S undercuts PS5DE by over $100 and Series X undercuts PS5 by $50, then it might manage to beat it globally in the US with the help of supply constraints.
I don't think Sony has revealed their entire launch/launch-window lineup. They still have some well kept secrets according to trusted sources. Not like they need those but it's something to keep in mind.
I miss these days, thank you XD
