It now public, and give you a nice overview on what's going on, where Oracle is going with Solaris and SPARC processors.

It's now available from here.

What can we lean from this roadmap ? well, if you look carefully:

• Oracle is announcing Solaris 11 this year. The release date should be ... check OOW11
  
• Solaris 10 updates should still be released in 2012 (remember, released in 2005). Check the Solaris lifecycle to understand how long is Solaris to stay side by side with Solaris 11.
  
• in 2011, a great 3x Single Strand improvement for the T-Series. Some thing great under preparation. Probably revealed at Oracle Open World 2011. Good news for ISVs !
  
• in 2012, a great 6x Troughput improvement for the M-Serie ! How can this be done ? ....

Nearly everything on the SPARC/SOLARIS level is said through the public roadmap,but as you know the evil is in the details ;)
