I am still confused lot of people are saying that vampire knight is coming out または not which is it?

If your talking about the マンガ then it's not coming out anymore because it's finished (unless there are extras または something). If your talking about the アニメ then I don't think it is either because nothing has been officially confirmed.

The マンガ is finished and the アニメ is finished as well あなた can watch it on watchcartoononline

vampire knight has been cancelled cuz' the マンガ insnt finished yet

The マンガ is now complete, though there have been a few additional bonus chapters since the official end.

The アニメ ended after 2 seasons, when the story had reached about halfway through the manga's story. It wasn't picked up for a third season.
