I'd say best way to do this is by geographic area. Considering the only one I know anything about is Chicago, I'd say Kirkland is probably safe. I think the other big boys there (Sidley, Winston, McDermott, Jenner, Mayer, etc.) will have some layoffs, but will otherwise survive. The ones that have already done layoffs might not be forced to do anymore, presuming we start to see an upturn within a year. I know absolutely nothing about the economy, so the year estimate is mere hope.
