I finally found the official Divas roster for WWE's Smackdown vs Raw 2011. There are 11 Divas. Which are: Alicia Fox, Beth Phoenix, Brie Bella, Eve Torres, Gail Kim, Kelly Kelly, Maryse, Melina, Michelle McCool, Natalya, and Nikki Bella.
I heard that Layla will be a downloadable, but, I did hear somewhere else she will be in it, but it just hasn't be confirmed yet. But I'm not sure.

If Ты want to see these photos, these are the Ссылки to each one:
