I feel the same way. Capcom games seem to also include dual audio most of the time seeing as how Ultimate Marvel vs Capcom 3 had dual audio for pretty much all the characters (especially the Capcom characters). Although, I do find it interesting for games such as Project x Zone and its sequel to only have Japanese audio and no English which is like the complete opposite. It's alright though, at least we can hear Lucina and Chrom speak in Japanese once again. Would be funny to see a English dub voice over of Segata Sanshiro though.I would love Dual Audio for future Smash games. But I feel like 80% of that issue is probably due to licensing and royalties Nintendo has to pay for voice actors for all that space but it's something I'll love considering even Sega can do dual audio for Sonic. The issue with Fates is due to Camila's Japanese Voice Actress.
Ah yes, Miyuki Sawashiro, one of the best voice actresses in the Japanese voice acting industry at the moment. I was a bit bummed out that they didn't include dual audio for Tales of Xillia and at first I wasn't a huge fan of the English audio but I eventually warmed up to it as I kept playing and started liking them. You know what I find funny about Miyuki Sawashiro though? She voiced Baby Beel in the Beelzebub anime and Baby Beel is literally a baby that goes 'waaahhhh', 'ahhhhh' & 'uuuuuu'. xDMiyuki Sawashiro is an expensive actress who has played incredible roles for her characters and has done them almost incredibly.
She's Cammy White, Ivy Valentine, Milla from Tales of Xillia, Elizabeth form Persona 3 and onwards, Squigly from Skullgirls, Catherine, Jolyne Kujo in all the JoJo video games, another Elizabeth but the Bioshock Infinite one and has major Smash connection as and She plays little Cereza in Bayonetta in which everyone should know who she plays as if you played the game.
