Hello ejay,
Generally they seem to send the review papers out about 6 months before the end date, so 6 months before November.

Edit: I have just read a post from a member who had review papers sent out about 10 months before the extended date. So my advice would be try and forget about it until the day when the dreaded envelope comes through the door.
