Richest Man in Japan Contradiction: 

"As of 2008, Yamauchi is the richest person in Japan and 149th richest person in the world, having a net worth of approximately $7.8 billion.[1]"

"He is currently the third richest man in Japan [2] due to his shares in Nintendo since their success with the Wii and Nintendo DS consoles."

These are quoted from the beginning and end of the article repectively.  I understand that they are technically both correct ("as of 2008" vs. "currently"); however, it would probably be clearer to state merely one or the other.
