plenty of JP releases have English subs
In fact a lot of Aniplex USA's releases are just the JP discs with the booklets and whatnot translated
I also rarely ever buy anything that doesn't have a dub. If I ever put in a dvd to watch it will be likely when I am going to bed or curling up with my wife, and at those times I don't want to read subtitles. I want to be able to understand what is going on without having to look the whole time.
For subs I will just watch it on places like crunchyroll... I think I own a total of like 10 series that are subtitled only, most of them were a mistake or dirt cheap... I think the house of five leaves was the only one I got willingly because I wanted to support NisA for releasing anime.
I am tempted to pick up yakitate japan when it releases though as long as the pricing isn't bad, as that is just to amazing of a series not to own
Yep, people who are actually fluent in Japanese and don't need subs and/or don't want to watch the English dub truly ARE a niche market in the US. Heck generally the only "extras" I check out on a dvd release are the "if you like this check out this" trailers because I've found cool series I've never heard of through them.
I watch my anime with subtitles on in general... it helps me when it gets quite and hard to hear people talking since I tend to either watch with people (talking with them which can mute out sound) or late at night (thus quite so as not to disturb people).
when netflix added closed captioning on their ps3 app I was quite happy and have since used it quite a bit more.
