Does Omnibus just repeat for grades 10-12?

I am just trying to get an overview of years to come. My oldest ds will be 6th grade next year and will continue with H.O. Middle Ages. I would like to use Omnibus in high school. It starts with 7th grade and goes through 9th and then I don't really see anything for the upper level. Are they not written yet or are there 2 levels in the same guide sort of like TOG? I am just curious about this. I don't really have to make a decision for another year. :)

The time period repeats for 10-12 grades. It will not be the same material, but the same time period. Omni I-III are written for the logic stage. Omni IV-VI will be written for the Rhetoric stage so it will look a little different. They are about to start writing IV and are anticipating it will be ready by the 2009-2010 school year.

Thanks. Now I just have to decide if I want to start it in 7th.
