Not a surprise. Further shows the PSN store removal was down to Sony, rather than CDPR's decision which is what they've been briefing.
Xbox haven’t made announcement because refunds on Xbox are easier to get. You just need to go on your order page and request it. I doubt they will be removing it.
Digital Xbox games are only eligible for a refund within 14 days of purchase, and Microsoft notes that submitting a refund request doesn’t guarantee a refund.

Heard a few people struggling to get refunds (probably due to sheer number who wanted one).
