Please define "Late Availability"...

I have done the searches which have a ton of hits and spent last evening going through most of them back to 2008...


I just ordered a 2015 F350 Lariat CrewCab Dually 4x4 with 6.7 a few days ago..
Some of the options like Bronze Fire Metallic with Caribou Accent paint showed "Late Availability".. There were no dates associated with these either..

Is there any definition as to what "late availability" really means?

Thank you in advance.. Hopefully others who have the same question will find this thread in their searches..
