I think it would be a good opportunity to make a (world)wider promotion for TNG on blu-ray by adding other additional language tracks and subtitles. E.g. Brazil is unfortunately left aside with a (on DVD) existing but on BD missing dub although it has a fast growing market for such products (I still think it's a marketing error not to have portuguese on the BDs). I think that there would be disc space still available for these additional language options.
It would/could be an additional convincing point for buying the disc besides the season set(s).
