It's interesting how them finally airing the entire series in the States revitalized series interest in Japan. DB and its spinoffs have had unquestionable global success, but after GT was done with the series was about ready to fade into obscurity. Now they're doing Anniversary OVA's and shit.

Sadly, now that they're doing all that, interest is waning here in the States. I'm hoping Funimation remains dedicated to it, otherwise a lot of the new stuff we aren't gonna see.

DB Heroes VM takes place around Goku Jr.'s time. There are tons of foreign games to America that keep Japan interested in DB.
I don't know why you and all these other Americans want DB Heroes to hit the states.
The game is pretty eh.
