Hi Claymore,
As things stand at the minute, the only version we're likely to see here in the UK (or anywhere except Australia for that matter) will be the Air Blowback bb firing airsoft version.
Retail prices here are unknown at the mo' but, knowing how expensive prices for Shoei products are, it's likely to be on the high side.
