The first 6 Star Trek films with, were possible, the director's cuts, and some indication that Paramount have actually spent some money and time on the quality of the transfers as opposed to the fan screwing, shit quality blu-ray releases they put out a few months ago.
The amount of titles available on Bluray at the moment is a fraction of a percent of the material out on dvd so there is very little selection at the moment.
The wanted list is huge but thats to be expected at this point in its life
