AllHipHop.com's Rumors section has this:

If you pay attention to the credits at the end of these shows, you will see that Diddy and Russell Simmons have been doing work in the TV world. In fact, they are making tremendous strides with stellar shows like "Run's House." I heard a rumor that Russ and Diddy are quite possibly going to take it to the next level. I heard they might be working on another label venture that will be based in Atlanta. So far, I have been unable to find information on this, so it could be a silly rumor. It could also be that base of power needed in the industry. Stay tuned…

Again, rumor, rumor, rumor... meaning, probably not true. But, I wanted to go ahead and mention it, anyway.
