My forecast was eight years.
Not bad, and I doubt they would have appealed, but there might have been grounds to. In the State vs Nesane, the perpetrator gained entry to the victim's house - his former partner who had intimated he was an abusive husband - and confronted her about her social crimes. The situation escalated to violence at which point Nesane picked up a gun, during the events that followed his wife was shot. He had clear sight of her and had intended to have an angry confrontation. He was sentenced to 45 years for murder, but on appeal it was reduced to 8 years for culpable homicide.
I think that there were probably more mitigating factors and less aggravating factors in Pistorius' case than Nesane's.
The actual term of imprisonment doesn't really matter much, he's finacialy broken, has lost his livelihood, his friens and good name . Plus he's got to live with this for the rest of his life.

True, but then there's Mike Tyson. A sport's cheat who won maybe $300million and was convicted of rape and served 3 years of 6. He lost most of it, but to call him financially broken is probably not quite accurate. Of course, many thought him innocent, so maybe that helped post-prison. Pistorius has a reasonable chance of doing OK for himself after his sentence, I think - much more than OJ did.
