Honestly I doubt she'll make it to SI. They've shot three times already for 2014 and she ain't there. I have my own personal reasons why I'm 90% sure she won't make it to SI, and even if she does being in SI is no guarantee of blowing up, just look at the last dozen of rookies, out all of them only Kate Upton has taken advantage of it and it was mostly thanks to her youtube video.
Also, It doesn't matter how many millions of people have seen the Blurred Lines video. People still don't who she is (or any of the other girls in the video for that matter) are ... The one person becoming a household name thanks to that video is Thickie himself. As long as people can't put a name on your face, you're a nobody.
If you're going by social networking or internet buzz then Ashley Sky completely crushes Emily in every sense.
