Is there a list of which specific ledger wallets will support this? I'd hate to get one and find out later it didn't.

As I understand it the Nano S and the Blue will both support it. This has been talked about on reddit /r/monero some. If you want I'll try to hunt up a link.
Thx for the answers guys, thats what I remember as well.
I'm in no need of one yet and If and when I do need one I'll more than likely build the open source one in design now. I just figured others in the thread should know which ones it's compatible with.
