Previously, there are HDMI to Mini Display Port converters for the 27'' iMac so that the iMac can be used as an external monitor. Anyone knows are there brands or companies developing HDMI to Thunderbolt converters so that the very new iMac 27'' can be used as what mentioned above? Just asked Kanex a week before and they do not give people even an estimated time for the release of the modified product but just said it will come out. I dont know if there is technical problem developing it so that eventually the product development dies. This bothers me a lot for whether to get a new iMac or not.
