Keep in mind that the cone is there to encourage people not to follow the black line. If one looks at the cone, they will see that there is a wide area being covered right now, including Texas, MS, AL and FL. It is entirely too early to speculate that New Orleans is in the bullseye right now. This track can and will change as factors such as shear, forward speed, ridges breaking down, etc. set in.
As far as I can tell, the cone has been shifting east -- albeit very subtly -- over the last 2 days. EVERYONE from Texas to Florida needs to watch this storm....and if residents living along the Gulf Coast have not gotten their supplies together, now would be a good time to do so.
