If Murray keeps playing this bad I definitely don't think he'll make the semis. He he has to go through Dolgopolov, Gasquet, and then either Ferrer or Isner. I think the top 3 contenders for the semi spot are Ferrer, Isner and Gasquet in that order. Ferrer is definitely the most likely, but Isner could easily upset him in the fourth round. Gasquet is a big threat to upset Murray, but even if he did I'm not sure if he could make it through his quarter final.
