Fancy new terminals, even fancy new ramp areas for plane movement but it is still the same limited number of taxiways and the same two intersecting runways that will still cause the same delays.
Not that JFK/EWR don't have their own movement problems, being stuck in a United push 27th for takeoff or JFK holding departures because of the backup of international arrivals.
Probably posting this because I have a 7p flight out of LGA today and am venting, start looking for thunderstorms now..
