They have already said that they will continue DVDs for shows where a BD isn't viable at all, so the format isn't being killed off entirely. Combo packs (which were mostly designed to wean people onto BD in the first place) and split SKUs, however, are clearly being removed to cut costs for the distributors. If the extra costs of doing combo packs or split SKUs have stopped paying for themselves, then it's no wonder that those release patterns are now on borrowed time.
In all honesty, I've seen this coming from a ways off. I mean, markets change. I've looked at combo packs and shows getting independent releases on the two different formats for a while and wondered how on earth it's profitable to sustain that model. Additionally, home video in particular has always been an area where technology dictates progress and change over time. So, most likely, I WILL end up addressing the situation somehow. Liek everyone else. My personal experience with external Blu Ray drives and player software hasn't been the best, mind. So it'll be something I look into with trepidation. Technology does my nut in.
I spotted on ANN in the discussion thread about Sentai's announcement (I think after it was the focus of an Answerman column) that Justin Sevakis has already chipped in on the matter, describing current software options as 'buggy but usable' - or something to that effect. There's nobody whose opinion and insight on video tech I trust more than Justin's, so that gives me some hope. One thing I do sincerely believe, though, is that if fans want to watch something that isn't easily made available to them, they'll find a way.
I also don't see BDs being all that more expensive than DVDs. They are, slightly, but on the other hand space savy and less weight on shipping.
I tend to notice a £10 - £15 price difference when I go shopping for discs online (which I haven't done properly all year.) In real terms for me, that's been the difference between picking up certain shows or not. It's enough of a margin for me to kill some impulse purchases. So in that sense, I do think asking price is a factor. Perhaps it's the cynic in me saying this, but I certainly don't see anime on Blu Ray becoming CHEAPER at any point.
Mind you, I DO see some potential positives. If anime on Blu Ray becomes the norm for the industry within a few years time, I'm wondering if, for instance, it might actually break down a few barriers. I gather that BDs are more expensive to produce than DVDs. But given how much more content can be stored on them, I wonder if it might do something to assauge the concern some distros have about certain shows being too long to release in less buoyant regional markets.
