I'll believe the TrueHD on the BD when I see (hear) it!
It *better* be true. If so, it would be Warner's first turn-around disc since omitting TrueHD from all the titles thus far where the HD DVD got lossless.
1080p/24fps still trumps all extras for me, so I'll take the BD version. I'm looking forward to either BD getting BD-J or HD DVD getting 1080p/24fps implemented, so I can stop 'settling'.
While the delay of BD-J is a bummer (as is the omission of the PIP interactive window in the BD release of this title), in the long-term it will be worth the wait. HD DVD's PIP is limited to standard-def resolution only, but BD-J will allow for a full 1080p24 stream for the PIP window (and bandwidth to handle it). This means that the player can down-res the 2nd stream for standard "PIP" mode, but you could also "swap" the windows and maximize the PIP window into the full 16x9 area with full 1080p resolution. This could be cool for work-prints and special effects sequences (ie, not something you'd typically be tempted to do with a PIP of the director talking in a chair).
They are both encoded 1080p/24. When Tosh gets around to releasing it's promised update for the XA2, I will have the same. Since my Sammy does not support 1080p/24, and never will, it is not loss to me.
A year after it's release, and stilling waiting. All this might be nice if it ever happens, that the studios will spend the time and money to produce all of these wonderful possibilities is another issue altogether. I will take what is over what might be any day, especially since the scenario you laid out has never even been promised by the BD camp, only stated as a technical possibility. The BD camp as not even released the final BD-J specs, they are not due out until early fall, it is all conjecture.
