The painful math of availability: when you start calculating the cost of pre-ordering a recent series about to land on disc, versus how much of your wishlist could squeeze into the same price.
I'm a touch tempted to nab the pre-order of That Time I Got Reincarnated As A Slime Season while the first part of season one is both available and cheaper than release pricing. But at the same time checking my Amazon list: the same price range when you factor in shipping (and Prime) would equal nabbing two series--older ones more likely to disappear. Where as Rimuru might disappear before I get around to acquiring it someday.
Many series see a western releases these days but I've generally find availability becomes a problem within the decade. One of my favorites is quite expensive and very scarce if you want the Blu-ray, and the series only aired ~5 years ago; even its license holder only offers DVD versions on their store front :'(. Many older series often I can only find DVD releases if they made a bargain bin recycle or apply a bit of careful hunting. One in particular on my shelf kind of fit both scenarios but over a decade ago, having been adapted from a visual novel that is now ~15 years old and quite damned unavailable today.
This leads me to worrying about how much good stuff might simply disappear.
Actually that makes me think about Robot Jox. As a film that impacted me greatly as a child, I kind of leapt at the DVD offering and was disappointed by the ultra-craptacular release. It was nearly unwatchable. And then bloody amazed when the Blu-ray came out with an excellent transfer--for a film so little known that I never really expected a post-VHS anything to happen.
Sigh. It's both a good and a bad thing that I don't buy many discs per year, be it anime or film. Actually, I'm pretty sure Marvel's release schedule would bankrupt me otherwise, lol.
