what's the story here, I can't seem to find consistent or verifiable info on these upcoming releases.

The Living Sea
Dolphins
Coral Reef Adventure
Fighter Pilot

I know that all the IMAX discs are not in the original aspect ratio but reformatted to 1.78 - oh well, what can you do? (not buy them? ), but seriousily... it appears that 'Fighter Pilot' has Dolby TrueHD... but what happened to DTS-MA? Image Entertainment has always been supportive of it's IMAX standard DVD discs to feature DTS. I know that Warner's has pretty much resigned their IMAX discs to not include lossless (earlier releases did, more recent titles: Cosmic Voyage/Destiny In Space and Space Station/Mission to Mir, no), but Image, they'd seem to be less asinine and have common sense to include lossless then the boneheads over at Warners.
IMAX's 70mm/hoizontal imagery and aggressive soundmixes seem ideal for bluray - so far though it's been a mixed bag.

side comment: the upcoming 'Baraka' bluray has been confirmed by DVD Aficinado to feature DTS-MA sound - hooray!
