Same here, Nvidia's sales plan is to try rid themselves of more 30 series before stocking the new 40 series.
"Rumour"
I believe some sites will be stocking around the 16th/20th December,... And, some sites maybe stocking when the NDA ends for the new AMD cards.
Saved for a new RTX4090 and the new standard ATX 3.0 PSU's and checking daily myself.
