The talk is getting louder. Oracle may swing an axe in the direction of its hardware division in 2017.
The key takeways here for me are that SPARC is likely dead and Solaris is probably heading towards permanent maintenance mode. The writings have been on the wall for a long time. For instance, Fujitsu the other main SPARC vendor chose ARM for their next generation K Supercomputer and for its part Oracle already uses Linux in their Engineered Systems and x86 processors from Intel.
