Docks? Or just stuff attached to TB? Once I move to a rMBP, I might have A dock just for the FW and additional USB ports. It has a HDMI out so that solves that problem... I do find wanting an additional TB on my cMBP though. As I do have a few TB drives but I can't use them unless I unplug my HDMI to minidisplay port cable. If you had two docks, you might as well get a MP at that point since it seems like you really need the additional ports.
