I think you are expecting too much change too fast. Look at how much data (nearly half of all DBMS data) is still stored in legacy DBMS systems. Yet it has been clear for nearly 10 years that RDBMS are more flexible and generally can match (and now exceed) performance of legacy systems. What must be remembered is that customers are relatively conservative and there will be significant opportunities for revenue for a long time (past 10 years).
For example, XBase support (Foxbase, dBase, applications, ...) are still probably selling at around 20-30% of the peak of this market. RDBMS definitely have not reached their peak at this time.
Further, there will be significant further development in RDBMS, because there are active standards committees (the draft SQL3 standard is well along), and a lot of R&D being done. In 5 year, it will still be easily identified as RDBMS, although there probably will be a lot more OR (object-relational) parts to it (there is a lot of OR in the SQL3 draft). In 10 year, there probably will be more that we do not readily conceive of, and the successor may be identifiable at that time, but RDBMS (and ORDBMS) will probably still be the king of the hill in the market at that time.
