Macbook Pro Refresh/Broadwell in the Fall? or Nah?

I'm thinking of picking up my own laptop, after years of not feeling like I needed my own. You know, if you work in IT, there's always a free laptop. Though, I need my own now, and I'm thinking of picking up one of the Macbook Pros. Possibly the 13incher, to focus my Web Development studies in that direction, and to just have my own machine. Though, are there any rumors, or news of the Macbook Pro line getting a refresh in the Fall? Especially with Broadwell. I know that's cutting it a bit close since Intel dropped the ball on the release date, but I just don't want to pull the trigger too soon if there's a refresh coming in the fall.
