Oracle buys Sun was an exciting accouncement 20 months ago.
What did change in the Solaris/Oracle Database world?
First, Oracle delivered Exadata on Sun Hardware (x86_64).
Second, they delivered Exadata on Sun Solaris Operating System (x86_64).
But now, they announced a combination of software and hardware that will run Oracle database faster than anything ever before.
I am happy to read Oracle is still investing on R&D on the Sparc processors server line !
