Quoted from Taxman:

No. What has always happed with CPR is they will not contact you until the playfields are done. They will go through them and grade them Gold, Silver, Bronze. Then they will contact batches of preorder people to the email address asking if you are still buying and what grade you want. You can put your address in the payment screen.
Read the order page on the website. The big change is if you pre-order and say you are not buying the playfield. Time until done is a crap shoot. They are supposed to get better (months) but in the past we have waited years to get playfields like TOTAN.

Quoted from Taxman:

Price difference on a game at that price has been around $50 per grade. If you go to the store you can see high end ones like TOTAN being $100 between grades and Joker Poker being only $20 differences.
But not they are doing something new with the difference in prices between Preorder and Leftover prices. They said they were changing the pricing and ordering structure to help them reduce completion times and maximize getting stuck with stock.
Lots to read on the website.
