It seems Sun Microsystems is continuing to support Drizzle. Drizzle is the MySQL fork that was announced at OSCON this past Summer. That said, Sun has been continuing to move developers to work on it internally (Jay Pipes, Monty Taylor). This is all good news. Based on the strength of the MySQL brand and history, drizzle stands to evolve into the next interesting database and Sun has a front row seat to best capture the upside.
[Update 11:20, 22 Oct 2008: Brian Aker just posted his assumptions on possible directions for Drizzle.]
