Yes, there's a possibility I'll go on for a doctorate (though not at BYU, because they don't offer one). Some of the PhD programs I've looked at require one language, some require two but don't specify what they need to be, and some require two specific languages, usually French and German. So those various requirements (especially the last one, which isn't compatible with BYU's requirement) make it a little hard to plan. Also, I think I'm most interested in doing research on Romance and Germanic languages, which is one reason why I'm reluctant to take something else just to fulfill the requirement.
And on the other hand, if I decide to stop at a master's and go back to work in the real world, some programming skills might come in very handy.
