I think there is good potential in BI. From what I've seen there is a want from employers to have a background or understanding of basic statistics. BI turns data into information via trends or other insights. Getting that data from one scope to the other with ETL tools is lots of planning. As a database developer you understand the importance and have experience with generating the correct datatypes and such to avoid space issues. So SSIS is something I think you can pick up with out too much effort. From there you can move to reporting if you havent already. Over time you'll learn when to create calculations in the report and when to do them in the procedure (depends on if other want the same data but not summarized as in report A made for department A only). So you interact more with the end user and that can be fun.
