When do you think S10 will be on Netflix?

I'm not sure if this is the right area to post this and I apologize if it isn't.

I was just wondering when do you think S10 will be on Netflix? I know its a bit early to ask this (especially since S10 hasn't started in the UK yet), but I was just curious because I just finished S9 and its going to take my PBS station a long time before it will show S10 (if it does...). Does it usually take a long time for a season to be shown on Netflix after being broadcasted in the UK? Thanks!
