OK, I found this in another thread:
The Dutch release is VC-1, OAR, 25GB, DTSHDMA 5.1
Edge Enhancement seems rather bad... but they are lossy JPGs...http://www.avsforum.com/avs-vb/showt...4#post18177484
The Japanese version is AVC, OAR, 50GB, DTHD 5.1
Comparing shots between the Japanese version and the Dutch version, it seems that the Japanese version is nearly perfect in comparison. Both are OAR and both have lossless audio, but the Dutch version is noticeably lesser quality due to the generic VC-1 profile smoothness and edge enhancement. The Dutch version also lacks extras. I guess I'm officially on the fence to either 1) wait for proper US release or 2) pony up the $60 for the Japanese version. Thanks for the help.
