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

If your talking about the manga then it's not coming out anymore because it's finished (unless there are extras or something). If your talking about the anime then I don't think it is either because nothing has been officially confirmed.

The manga is finished and the anime is finished as well you can watch it on watchcartoononline

vampire knight has been cancelled cuz' the manga insnt finished yet

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

The anime 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.
