Now that the new 2010 Mercedes-Benz E-Class is officially on sale here in the U.S., it's time to start the countdown for the next soon-to-be-released model.  That model, of course, is the 2010 Mercedes E-Class Cabriolet, the drop top version of the Mercedes E-Class Coupe that debuted back in February.

Unfortunately, there's no clear confirmation as to when the model will be officially unveiled – some rumors place its premier at the Frankfurt Motor Show this fall; others think it will be next March in Geneva – but whatever the case, here are the latest nearly undisguised photos of the model.

As always click any photo to enlarge, and stay tuned for more information on the 2010 Mercedes E-Class Cabriolet as it becomes available.  Also, after checking out the pics below, head over to FastestCar.com where you can check out the full E-Class Cabriolet spy photo gallery (thanks Andrus).

Enjoy.
