This is fresh news, Sun just bought MySQL. Here is the the official press release: Sun Microsystems Announces Agreement to Acquire MySQL, Developer of the World's Most Popular Open Source Database

Kay Arnö, responsible of the community behind MySQL, writes about what this means for the opensource community, both developers and users: Sun acquires MySQL

Sun has a proven track record of supporting OpenSource as whole, so I guess this will help (if it ever needed) an even better development of MySQL DB engine.

Congratulations MySQL!!
