You can never tell - last year we booked for this coming Oct just days before the offer ended, then it was extended, and improved, with $150 spending money added.

I have no idea what will happen this time around... There already is $200 included, so the deal looks about as good as it will get, but that's not to say it won't be extended. Or maybe bookings heve been brisk enough and it won't be. Anyway I'm not booking for next year at the moment. Don't know what to do yet, and I guess we'll stay offsite if there aren't any offers if/when we do book.
Congrats to those who have booked though - it's a great deal
