HD Audio - do any Blu Ray discs make use of it?

[admin_exported]

Sorry about this really crazy question but reading the AV amp reviews in the Awards issue, they have wept my appetite for the wonders of HD Audio. Problem is the BD discs I've looked at currently (mainly blockbusters) seem to be still DD 5.1. Are BD discs supported the higher HD DD and DTS standards yet? I've seen a DTS HD logo on the back of the Pirates movies but would these be specifically highlighted or are we seeing mainly transfers of the standard DVD soundtracks at the moment?

 It would be a shame to invest in too many BD's only to have them re-issued in 6 months time with better soundtracks! I've seen suggestions that Indy 4 will have an HD audio soundtrack of some time but is this something that will creep in over time?

Virtually all Blu-Ray movies carry an HD audio soundtrack. There are a few around which only carry Dolby Digital (The Island and Mission Impossible stand out in my memory), but most carry either a Dolby TrueHD, DTS HD Master Audio or uncompressed PCM soundtrack (or a mixture of the three).
