What are your thoughts about this?

Very few MBAs have majors and minors. I don't think specialisations matter as much as the quality of the school.

If you're talking about a concentration / specialization in Entrepreneurship, there are a lot of them:

I think they can help certain candidates achieve their goals. But I wouldn't suggest that everybody do an MBA with a focus in Entrepreneurship. What are your goals?
