Draykon by Charlotte E. English
Auracle by Gina Rosati
Sweet Shadows (Medusa Girls #2) by Tera Lynn Childs

I am too lazy this time around to check when all of the above covers were revealed but I know Draykon came out in 2010, Sweet Shadows was revealed back in January (where was the blogosvere mania for that one? Sweet Venom certainly got more attention last year) and will be released in September. As for the others I leave that to google if you're really curious about them and will only say I think they are very pretty.
