Eh, somebody will dub it. Anyway, there is a large anime following in the U.S. that is quite happy with Japanese dialog tracks. At SF conventions, it was quite common in the anime film rooms to have a synopsis passed out for those who didn't know Japanese and wanted to see the films.

In fact, when a Japanese animation film is released on DVD with a dubbed track in the U.S. (as with most of the Miyazaki films), purists get ticked off if the option to watch in the original Japanese isn't included. The Disney Miyazaki releases do include Japanese tracks, and subtitles from the Japanese. Interestingly, the subtitles do not always match up with the closed-captions for the English soundtrack, and it's fun to compare what was added and what was left out.
