Should i buy the English subs for vampire knight (anime) or wait and see if it comes out in the US?

I suggest you wait until the dubbed version is out. Then watched the first episode subbed, then episode 2 dubbed on the internet and see which one you like better.

Yeah I'm not the only Vampire Knight fan but I did know that it was gonna be a anime soon and I hope what they say are true but I'm kinda picky cuz if Kaname and Zero's voice arent how I imagined them to be I won't whatch it

I always prefer subs to dubs, so I'd suggest getting the subbed version. Subtitles are sometimes more accurate than dub-overs, especially when it somes to japanese puns that make no sense in english (not that there are any in VK, it's just an example)

Not yet.

wait and see if they come out in the us
its always better and sometimes the dubs arent
accurate

I would say to wait until it comes out in the US. Until that time comes read manga online at mangafox.com or watch some more shows at justdubs.net
