That's not really accurate since the LM7600 is not on par with the LA7400. The LA7400 has a dual core CPU. Also the remote has voice recognition. Both of those features were only available for LM8600 and 9600 in the 2012 line.
According to the info released so far, the 2013 tvs are supposed to have an even thiner bezel. From the pictures I've seen the bottom trim is smaller. CPU and GPU performance is greater. The Magic Remote has been refined. The Smart features have been redesinged. etc etc etc
Of course all of this will have to be confirmed once they are out but to me unless you are in a hurry to buy, waiting is the best bet.
