Since we are refocusing, I'll begin.

I think that the MCJ should be broken down into to certifications; MCJ DBA/Developer and MCJ BI. As you progress in your career field there will be a merging of specific skills across specific boundries. This is particularly true between DBA and Developer as both will begin to learn to write better performing code, creating better indexes, reading and understanding execution plans, etc. The BI world, however, I don't necessarily see as much cross over with DBA/Developers. Especially since MDX queries are your fathers SQL queries.

Both should require a core understanding of the SQL Server Engine, T-SQL, Indexing, but not necessarily to the level of a DBA/Developer.
