Almost two months after his shock arrest in Tokyo, Carlos Ghosn remains at the mercy of the Japanese legal system as prosecutors continue to build their case against the car industry titan.

A Tokyo court extended the detention of the former Nissan Motor Co. chairman for another 10 days on New Year's Eve after he was re-arrested on fresh charges Dec. 21. Meanwhile, Ghosn's former aide Greg Kelly, who was detained with the executive back in November on allegations of helping him under-report his compensation, was released on bail on Dec. 25.

So, what's next for Ghosn?
