Of course not, because as the NHC and others have said for days, once the system becomes extra-tropical the wind field will expand, but at least as far as the lowest SLP that will be wherever it makes landfall in the next few hours...

Well the windfield is already huge, that quote I posted about hurricane force winds extending 175 MILES OUTWARDS was from the 2PM advisory while Sandy is still a hurricane...that swath of strong winds will only increase. But whether or not it becomes extra-tropical before landfall is irrelevant as hurricane force winds will extend to NYC. Bryan Norcross on TWC just showed a graphic illustrating the water level at Battery Park already at 6.7 feet, almost 2 feet higher than its peak during Irene. Remember, that the most destructive aspect of any hurricane is storm surge and a southern landfall with respect to NYC makes things only worse...as OzonePete alluded to:
an earlier arrival could actually be just as bad or a little worse. If the winds stay up very strong for a few hours after landfall (which is highly likely due to it's becoming hybrid), as the center comes ashore near Atlantic City the winds will turn to southeast here and that will push the water directly onto the local beaches and up into NY Harbor. So water could be piling up extraordinarily high as high tide comes in between 8 and 9PM tonight.
