My dealer provided me with the same date that COTUS has been displaying from the beginning - January 26. I can give you a firm answer around that time. At this point, I'm waiting for the status to change from "in production" to "awaiting shipment" as the build date was scheduled for This past Saturday.
COTUS has a lot of potential, and everyone I talk to is very impressed with the details it provides. IMO, it is still very much a work in progress as I've mentioned earlier that it has proven to be very flakey. Still to this date the window sticker button never worked for me, and sometimes can't find my car unless I refresh it 10+ times. I'm sure it can't be an easy feat to consolidate this information from the various assembly plants and have it available for us to see. It does a lot to build excitement as your vehicle goes through the phases, however as many have experienced, can be very frustrating when things go off the rails so to speak. Great innovation and effort by Ford nonetheless, but my opinion may change after the 26th depending on what happens
