Correct, dealers don't pay MSRP. They DO pay for the product, plus whatever the manufacturer has to do to the product to make it legal to sell, plus whatever government red-tape they have to unravel to get the product.
Kel-Tec isn't going to send those RFB's back into the shop for grinding off caliber markings or re-reaming chambers for free. They'll charge, Vault will pay them, the dealers will pay Vault, and YOU will pay the dealers. None of the links in this chain will stay in the chain unless they make a profit...as offensive as that may seem to many folks on this forum.
Will this raise Vault's per-unit-cost up to the level of the MSRP in the states? I don't know, and I'm pretty sure that nobody else here knows either...SO RELAX! Have a Kit Kat. Don't worry about something that you can't control, especially when it hasn't happened yet and probably won't.
