Can we just have 3D sound now, with X, Y and Z coordinates to go along with the sound clips, and the speaker system routes the right sound an arbitrary number of speakers? That works amazingly well for FPS games...

A feature film could easily have a hundred different layers of audio at any given time, maybe more. The storage requirements would be INSANE.

  To me, hundred high-quality audio channels with lossless compression sounds not "INSANE" but "still less than the video". Playback processing might be tricky, streaming might be tricky, but actual storage for any movie or home cinema setup should be trivial. You can easily put a hundred audio channels on a fraction of a bluray disc, not counting any future improvements in storage.

    >To me, hundred high-quality audio channels with lossless compression sounds not "INSANE" but "still less than the video". Well, 100 audio channels 50% lossless compressed files would go about 60 GB for a 2-hour movie. So not really "less than the video". And that's for 16/44.1 lossless. For 24/96 adjust accordingly. (Of course not all 100 channels will have sound playing all the time -- except if we're talking for a musical or rock concert video. But it gives a taste of the max storage requirements).

        Sure, but why compare it with losslessly-compressed video? That's just for editing -- all viewing formats feature lossy video.

        In fairness, they also feature lossy audio, although that's less of a ratio around 6:1 for a typical consumer DTS track, maybe 8:1 for AC-3/Dolby, compared to 5000:1 or more for video. (Uncompressed 6 channel 16/48k is ~4Mbit, typical DTS is 750kbit, occasionally 1.5Mbit, AC-3 is around 450-500kbit)
