Got a response from Playstation Gear US, which is apparently run by ThinkGeek. Someone nicknamed "Brick". Not good news.

Hello,

I'm sorry about that! Unfortunately, that merchandise is only available on the UK store. We are not currently offering it, please let me know if you have any further questions.

I know AdHoc has offered to help me import. Anyone else? After all, I can't be the only one who wants these in the USA.
