Sorry if this stating what Basil Fawlty called the bleedin' obvious, but I'm going to state it anyway.
The only reason why the DTS system was based on data storage using CDs, is because when it was launched in 1992 there was simply no other viable way of shipping that much digital data from distributor to cinema. Cinemas were willing to faff about with CDs because the higher bitrate of the audio data and the more resilient timecode reading gave it a significant advantage over Dolby and Sony.
How big is the longest DTS soundtrack you'll ever really need to transport from A to B? Around a gigabyte, I'd guess. The Internet can now shift that volume of data in a few minutes, even to a domestic household. From this thread it's becoming obvious that the unreliability of CD deliveries is a major problem. Unless they want to continue losing market share, surely it's time for DTS to abandon the offline delivery model and replace it with two alternatives: 1 - a secure server from which approved venues with a username and a password can download ISO CD images to burn for use in existing players, and 2 - equip new players with a hard drive and a direct Internet connection, so they can download the audio data directly and play it back from a local hard drive (or even RAM).
Whereas we've probably reached the limit of the amount of audio information we can put on a film print itself (both in terms of the optical data itself and the extent of lossy compression), the timecode synchronised to an external processor model still has life left in it, IF the problem of delivering the data to the processor reliably can be solved.
