The plain white Corvette is being released in the UK. I believe that only a very limited number are being brought over, though I would guess this could just be to test the market.
If they are popular, I'm sure more will be brought over.
As to why they might be more popular in the US, I don't know. I would tend to agree with it though, we don't get many enquiries about them, and the previous ones don't seem to generate that much interest (on eBay for example).
This would suggest that the main Sport editions are imminent though.
