Wow... I didn't think that dubs would be that big of a deal. Personally, English dubs isn't something that this game needs. Especially if they're gonna be as bad as the ones from KOF XII. Those were really awful.
Here is my stance on dubs:
Half of the time, the original Japanese voices suck. (Look at Yuri for example, her Japanese voice in the KOF series is annoying). But seriously, this dub bashing is getting old, and the only people that hate dubs are those that watch subs, you guys really need to get used to a dub, even if it is bad.
What this game needs in a future update is a good English dub, and judging from the KOF XIII pre-order sales, that might happen. While I do respect those that like subs, I prefer dubs more.
There is a reason of why Japanese games have a voice language option, so you can switch to the original Japanese voices if you don't want to use the English voices, but people like me will keep the voices to English.
And while I do like subs, they happen to suck half of the time, so in my stance:
Fuck subs, live with a dub. (Counter to MUSOLINI's "Fuck a dub, live with subs")
