Does anyone know when Z77 motherboards with Thunderbolt will come out?

Hello,

I think that Intel Thunderbolt is a really interesting tech and I heard that Ivy Bridge and Z77 would be bringing Thunderbolt to a wider range of PCs than just Apple's, and am looking to buy a Z77 board with a Thunderbolt port on it for my PC build.

Problem is, the current range of Z77 boards that are out don't seem to have Thunderbolt ports on them and the only board that I know of (a board by MSI, the Z77-GD80) that has one isn't out yet. Does anyone know the current situation of mobos with Thunderbolt?
