BB Corporate Finance Exit Opportunities

I currently have an internship offer at a top BB think (GS/JPM/MS). Ultimately, it is a corporate finance position. I was wondering what the exit opps down the line could be if don't want to be in CF forever. What are the chances I could break into MO/FO Treasury/S&T/Equities Research/Asset Management? I think IB would be a long shot coming from a relatively BO/MO position. Do I need to pursue an MBA to move up? Any feedback will help. Thanks
