I've never seen B-Daman so I can't comment on that. But isn't B-Daman even more unknown then mainstream Bomberman is? In that case, it just isn't very likely for the cartoon to get over here, since not many people would "get it."
If you ask me, the only Bomberman cartoon that had a chance of coming to the States was Jetterz. But since the GCN game didn't do so well, they never brought it over here.
