Buffett has been planning this since at least 2011:
CHICAGO (MarketWatch) -- Warren Buffett has told the CBS News program "60 Minutes" that after he dies, he wants his son to become non-executive chairman of Berkshire Hathaway. Howard Buffett, a farmer with no college degree, would be a good successor, the elder Buffett said, because he understands the values of the company.

I’m not usually about hereditary succession, but this is an exception I could get behind.
