Yes, economics is the only thing that matters. That's how I know the originals won't be included, it's bad business. Unlike TOS-R, they'd be duplicating content currently available that they're already trying to sell you. They'd be going out of their way to provide material that doesn't meet the standards of the Bluray format (it wont sell the release). And they'd be doing it at an unreasonable expense to themselves and consumers, as it would take 2-3 extra discs per season to be able to include them.
They already put standard-definition materials on their BD releases. All the previous special features from the DVDs are on the Trek BD releases, and they're still in standard def, which according to you, shouldn't have happened since "they'd be duplicating content currently available that they're already trying to sell you". Most studios are doing the same thing.
Hell, even the Ultimate Edition
Harry Potter films on BD include a plain old DVD of special features since they just ported pretty much the same disc over from the previous release. And Disney BDs include a full DVD of the film on top of the BD and digital copies.
Don't act like you're an expert on the home video market or BDs when you make obviously incorrect statements.
