Just because someone has a retina MBP doesn't mean they want to or can use all the Thunderbolt ports for displays (Retina MBP doesn't have an ethernet port so you potentially already need a dongle to tie up one of the ports for that). A USB solution is cheaper and more extendable through hubs.

Granted, I'm not a driver developer, but I want to know what the hold up is for OSX and Linux. Obviously it can be done since the 2xxx series chips work with both. Is it an issue of demand? Or is there some technical hurdle that needs to be overcome? I would think this would be a higher priority given the number of additional customers this would give you.
