PS3 does support DTS HD, but not DTS HD Master Audio

I figured there were not TrueHD 7.1 movies, but that's not really the point.
If there ever would be a 7.1 TrueHD movie released, what would happen when played on a PS3, downmix to 5.1 or will it be 7.1? Same question applies to 7.1 LPCM.

I didn't know DTS-HD was supported, because I didn't see the logo on the PS3. Just the regular DTS logo (no HD imprinted).
And is DTS-HD possible over TOSLINK? Or is DTS-HD only available via HDMI?

7.1 LPCM is currently supported with the PS3. If a DolbyTrueHD 7.1 were to come out, I assume that the internal decoder would decode all 8 channels of audio and then send it to the audio receiver via HDMI, but we won't know for sure until we actually see a Dolby TrueHD 7.1.

The PS3 is capable of processing a DTS HD hi res (1500kbps of compressed audio, not lossless) which is less compression compared to a regular DVD DTS audio(around 750 kbps)
