4 years on, his abs have set sail, his calves disappeared, he grew a GUT, he aged 15 years

You're a moron, he was probably at his best ever at this years Arnold. He added a lot of thickness, quality and muscle maturity to his physique, it's night and day compared to 2007.
The only problem is his left calf, that one is gone for some reason. Other than that he has improved in every aspect.
