Stonebraker et al have an interesting paper pointing out the antiquity and consequent limitations of the classic relational database architecture in today's world of massive disk/cycles/core.
If they are correct (and in spite of the recent MapReduce blunder Stonebraker has made a lot of great calls in the DB world), the world of data management is going to get awfully interesting in the coming years. The DBA's & DA's of this world have been living a relatively comfortable existence compared to those who are wandering across the stormy badlands of the middle tier. But Stonebraker postulates at least 5 radically variant database architectures to address specific use cases of data management. This would seem to lead to a much more complex world for data architects. But maybe a windfall for the consultants who find their niche?
