As for the A's thing, I think that Larry Baer (even though I'm not a big fan of him) has a right to protect the Giants from a business standpoint, especially if the A's being in San Jose could take money out of their pockets. If the A's do get to go there, I hope the Giants at least get a deal cut with them like the Orioles did when the Nationals moved to DC. Another potential arena is a possible Golden State Warriors arena in San Francisco, which would help fill the city's financial void that will left by the 49ers. We haven't even brought up socal stadium issues (Angels, Dodgers, Chargers, NFL). You're right that California's stadium landscape could look VERY different a few years from now.
