Okay, what I'm not getting here is why they simply can't include both the original, unenhanced, SD originals and the new, spiffy, HD, CGI-enhanced TNG-R versions and be done with it.
If you're going to do a release on DVD that includes both a new version and an old, you either have to go the 'seamless branching' route or you have to add alot of extra discs because of capacity issues.
But as has already been pointed out, a Blu-ray disc has plenty of capcity to hold 4 or 5 HD remastered enhanced episodes, the original versions of those same episodes in SD, and any extras they want to include, all on the same disc.
All Paramount has to do to placate those purists who want the originals is to toss the exact same versions as used on the DVD's onto the Blu-ray discs. No new editing, no new transfers, no new visual effects, not even extra discs. There is no economic disincentive what-so-ever to Paramount to include them.
