Thunderbolt to HDMI+USB adapter?
So, here's the catch. I'd like to connect my retina macbook pro to my home studio (the studio is compiled of a lot of usb devices and one video input [HDMI]) using one cable only. All the other ports need to be open. I know this could be achieved with a thunderbolt dock, but those docks are way to bulky and have too many useless features I won't be using. So my question is are there any thunderbolt to hdmi+usb adapters, or will I have to wait?
MacBook Pro with Retina display, Mac OS X (10.7.4)
