It sounds to me like your player with Dolby Digital TrueHD circuitry should be able to automatically output uncompressed PCM over analog or digital connections, including HDMI 1.1 or higher. Your AVR just plays the PCM bitstream and doesn't perform any of the de-encoding. From the Eggers interview though, it sounded like future players will be equipped with an option to bypass the "de-encoding" process and send the TrueHD signal directly to your AVR. In that case your AVR would need to be equipped with TrueHD circuitry, but I would think you would still have the option of analog or digital interfaces (including HDMI 1.1, 1.2 or 1.3).
In an article I read over the weekend, however, this is apparently not the case with DTS-HD Master Audio. This bit-for-bit lossless format apparently produces a bitstream of 24Mbps, which will necessitate the higher capacity of HDMI 1.3.
So, if I had it my way I would let the player do the task of sorting out the bits and feeding the AVR an uncompressed and clean signal. The less processing going on in the AVR the better, and the less often you will need to upgrade the AVR. However, your player will likely need to be replaced every 3-5 years (or less).
