I suggest going ahead and getting this one, cause who knows how long it will be before the HDDVD version. However, they have the 4k raw data..something like 300 TB worth of data stored, ready to use.
The only thing I don't like about this release is there is still alot of grain. I mean, I like grain, but I would figure they'd be able to clean alot of it up. It becomes less noticeable in the Technicolor.
