my guess is they've started if not already come to an agreement on rent negotiations, seeing as how it would be catastrophic for banks if their building leases and mortgages went into delinquency. at the prices comcast is paying, they have all the leverage.
on one hand, renegotiating rents would likely save a number of jobs. but on the other, there are bound to be cuts as productivity and revenue by division are going to be under extremely intense scrutiny. if you've been coasting, now is the time to either grind or prepare for your next career move.
