I just recently found out that this wasn't a new thing. Maid in Heaven SuperS which was released back in 2005 by Green Bunny had 2 audio streams for both the Jap and Eng Dubs.
I hope someone could tell me about other titles that also have multiple audio streams. I'll make a list here and make updates when necessary.
