Creative decision I'm assuming. It costs less to just release it here with the original Japanese cast, instead of hiring another cast of voices just for North America, where these games don't sell nearly as well as they do in Japan. From a business standpoint, it makes a lot of sense. Bringing all these games to North America costs money to translate it, and then make copies of the game that don't sell really all that well over here, to hire a voice acting crew just makes it more expensive. So I don't know if we will ever hear English VA's again.
