I recently had an extended conversation with my neighbor, who works at Dolby Labs here in San Francisco.
In the course of our discussion, I took my usual opportunity to bemoan the decline of DVD-A. He informed me that their Dolby TrueHD offering is based on MLP Lossless - also the core of DVD-A technology - and has been further enhanced with better data rates and channel options.
Thus, it now seems DVD-A is far from dead. This is likely old news to Stereophile staff members, but I no doubt missed the memo.
