Even if the packaging includes both the Blu-ray and the DVD, the Blu-ray only extras aren't on the DVD because, well, they're Blu-ray only extras.
So that sort of packaging won't help DS fans without Blu-ray players if there are Blu-ray only extras when the film comes out.
I'm sure that, when it comes to people who don't have a Blu-ray player but who plan to buy one eventually, it's nice to get both in one package because then they can at least watch the DVD version, and then when they get their Blu-Ray player, they'll already have the Blu-ray version. However, most Blu-ray player owners that I know, myself included, prefer to buy the Blu-ray only package, if one is available, because the DVD will probably never get played. And it's somewhat aggravating whenever there is no Blu-ray only version released because more often than not you have to pay extra for something you're never going to use. About the only time it's less aggravating is when one side of the disc is Blu-ray and the other side is DVD because in those cases they don't tend to cost more. But in my experience, many times the Blu-ray and the DVD are separate discs.
And this is more OT than not so I'll keep it as brief as possible, but while it was at 56% discount last week, I ordered the Blu-ray/DVD Combo + Digital Copy of the 4th season of
True Blood from Amazon because there isn't any Blu-ray only set. However, I paid the same price for it as I paid for the 3rd season Blu-ray only set, so I'm presuming it's going to be Blu-ray on one side and DVD on the other. But it's going to be very interesting if it isn't...
