We're still over 24 hours away from CBS making their official announcements about the new season, but apparently pre-upfront news is as plentiful as upfront news, so here we are with more information about what CBS will be telling us tomorrow. In addition to the already leaked three dramas that are a go -- Alex O'Loughlin in Three Rivers, Julianna Margulies in The Good Wife, and LL Cool J and Chris O'Donnell in the NCIS spin-off -- today we've learned about three more new shows.

Jenna Elfman is back on TV with a new sitcom. In 2006, she tried a CBS comedy called Courting Alex that failed to click, but she had a five-year run on ABC with Dharma & Greg. The actress toplines Accidentally on Purpose, playing a film critic (and I hope whatever publication she writes for doesn't go belly-up like so many others these days) who accidentally gets pregnant after a fling with a younger man. I'm laughing already.

There's also a Jerry Bruckheimer medical drama called Miami Trauma. That means two medical shows for CBS; Three Rivers is about organ transplants. The Miami part is interesting to me because obviously the conventional wisdom is that anything set in South Florida must be glamorous and exciting. I live in South Florida and I don't think that's true, but Mr. Bruckheimer knows something about making hit TV shows that I don't know, so Miami it is.

On the reality front, Undercover Boss is reportedly on the schedule. It takes corporate executives and puts them in the lowliest of jobs to see how they react. Apparently this was a big hit in England, so here we'll get the American version.

Finally, the last new project leaked is called House Rules, about a freshman class of representatives in the U.S. Congress. Mark Gordon (Army Wives, Grey's Anatomy) is producing. The last attempt at a Congress drama was Josh Brolin in Mr. Sterling on NBC. It didn't last a year.
