Here are some various links on the sale of the A's to Lewis Wolff. The ticket price is rumored to be at $180 Million, almost double what Schott y Hoffman paid for it 10 years ago - depending on which reporter you read and believe.
"Major League Baseball approves the sale of the Athletics to a group headed by Lewis Wolff. Fans hope he'll be willing to keep the team's top players -- and keep the club in Oakland.." - emphasis is mine, but the second period is the Chronicle.
What you really need to know is that Kaiser Bud Selig doesn't call for a vote unless he gets unanimous decisions one way or the other. The approval of the sale is basically a back of the hand gesture until Wolff decides to begin making waves, if any. The paperwork still needs to be signed and Schott y Hoffman still need to have their moment in the sun.
There are developments on the horizon, including the actual majority owner, John Fisher of the Gap family fortune ("cheap fabric and dim lighting - that's how you move merchandise..." - Morty Seinfeld), into the team that may or may not be a path toward a new stadium.
