it seems like the Pro Display XDR is discontinued. The webpage for that now redirects to the Studio Displays XDR

There is a note at the end of the linked announcement:

”Studio Display XDR replaces Pro Display XDR and starts at $3,299 (U.S.) and $3,199 (U.S.) for education.”

I can't find it either.

Which means they don't have a 32" display option if true.

Maybe it will also be updated, but on a different day this week?

On the announcement page, they say "Studio Display XDR replaces Pro Display XDR" in the footnotes, so doubtful.

They could be considering the new high end display a different product rather than a refresh (for marketing purposes at least).

I recall the XDR being announced alongside the last Mac Pro redesign. No new Mac Pro yet, so maybe they’ll announce the new large display whenever that is announced?
