Ford will soon announce a new model for the 2013 F-Series Super Duty line, but for now all we have is this teaser photo of the truck under a sheet. Ford says the new model will be properly revealed Friday, March 9.

The dark sheet covering the Super Duty pickup truck precludes us from telling what changes Ford has in store. Given that we can't actually see the car, we'd guess that this teaser image means that the toughest F-Series trucks will receive some sort of visual makeover or change.

Ford plans to unveil the 2013 F-Series Super Duty in partnership with the Professional Bull Riders; Ford sponsors the organization's Built Ford Tough Series that is effectively the "major league" of bull riding. You can watch the truck's reveal next Friday at 10 a.m. Eastern / 7 a.m. Pacific via a special webcast.
