I'm looking to buy a TBD next month. But since Apple just released the Retina MBP, I'm unsure if a TBD will follow with retina shortly. What should I do? I've been saving for this for quiet a while now, and don't really want to wait till summer 2013 or something.. Also, what are the possibilities to daisy chain a third party monitor to the TBD? I've read somewhere, that if you put another thunderbolt device between the two monitors it should work. Is that true? If so, what device should I get? I don't need any accessory. So the whole purpose of the device would be to connect the two monitors. Is there anything real cheap?
