Looks like IBM and Sun have an agreement, finally!
"Big Blue will bring versions of its WebSphere Java software, DB2 database, Rational developer tools and Tivoli management tools to Solaris for x86. IBM already supports Solaris on computers with Sun's Sparc processors, but decided to create the x86 version based on customer demand, Steve Mills, a senior vice president in IBM's software group, said in a statement. IBM will support Sun's latest version 10 of Solaris for x86 and Sparc."
btw: similar agreement was annoucement last week with EMC, which is great too.
