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 u want to see these photos, these are the linken to each one:
