Some thoughts:
Even with hurricane Sandy and its wide impacts, things will indeed get worse. The US coastlines as a whole have actually been very lucky with respect to hurricanes since 2005, with aggregate damage (even including aggressive estimates for Sandy) 2006-2012 falling at or below the historical average. Sandy made landfall as a post-tropical cyclone of hurricane strength -- a phenomena that has only been documented 3 times since 1900 (1904, 1924, 1925 -- later this week I'll have a post on Sandy damage estimates).
The long-term intense hurricane drought means that a mere "regression to the mean" will see more hurricane landfalls and considerably higher damage in the years to come. The fashionable talk these days of a "new normal" is of course utter bullsh*t. Just wait until we return to the "old normal" -- I know that it may be hard to believe, but both hurricane damage and climate hype are set to increase dramatically in the years to come.
