Loretta Hunt, who has moved over to Sherdog, reports that CBS is hoping Elite XC pulls in three to four million viewers:

Kahl said the easiest way to measure EliteXC's success will be to hold its ratings up to the current Saturday night programming's marks, though the network is hoping to see "increased younger demographics."

With that, Kahl said CBS hopes to net three million to four million viewers when overnight sensation Kevin "Kimbo Slice" Ferguson slugs it out with James Thompson (Pictures) on May 31.

Let's call this what it is:  The lowest numbers acceptible.  This is the beginning of the effort to set the bar low for expectations, so that if it comes out at 3 million viewers, they can claim it was a success, even if it wasn't.  Still, we now at least know how to define failure:  Below 3-4 million viewers.
