So Is There Going To Be A Season 3 Of Vampire Knight Or Not? And If There Is When Is It Coming Out Or If It Is Already Out Where Can I Get It?

There's unlikely to be another season of Vampire Knight in an anime. The story does continue (and is por now complete) in mangá form, though.

No,because at the end of season 2 you see them walk off and besides it was all about yuki being awaken so what is there mais talking about unless her and kaname have kids and they have the same problem has yuki or if yuki find out that zero loves her and she find out she loves him mais than kaname and she has to go and find him so she can tell him how she feels before he trues into a leave E.
