Seems like the traditionals haven't been able to survive the second wave of disruption. This is what is prompting the merger i.e. if you can't grow like the fintechs then cut costs using merger cost synergies. A side effect of this is move from extremely high cost locales to lower cost ones. It's PR couched in terms like "Any additional real estate decisions will be made as part of the integration process, over time."
Good for San Fran and the bay area, it seems. Some prime corporate space being vacated should take a little pressure off real-estate prices (I hope).
