A plug-in card that contains the new DTS and Dolby immersive codecs would be an interesting concept. Buy the new pre/pro in the near future and then IF you want to invest in additional amps and speakers for the new codecs, buy the plug-in daughter card when it becomes available. What was the old high-end pre/pre that was designed for plug-in upgrades - Theta? Outlaw could do it for a reasonable price. I won't be going Atmos or X in the near future, but would like to have top end audio in a new pre/pro without the cost of the codecs/processing built in.
