Here's what I think happened..
They over produced the PCR Vader helmet in hopes of high volume sales to offset the production cost of the scout and begin production on their other pre-orders.
When they weren't selling (as you can tell there are plenty available in third party stores) then thought, "hmmm...in order to move the overstock on PCRs, lets Chrome them and make them exclusives to make them even more desirable with a higher cost."
Now even the extremely limited 500ea Chrome CCI exclusives are STILL available on their website.
For what its worth, this is telling me they are out of money.
Purchase from them at your own risk
