"Top Model" was not only renewed for a cycle 13, but 14 as well.
"Smallville" was in the bag after the network secured the return of star Tom Welling (Clark Kent). Two of the showrunners, Darren Swimmer and Todd Slavkin, are moving off to "Melrose Place" and if that one picks up, co-showruners Kelly Sounders and Brian Peterson will takeover.
"As we continue to build the CW Network as a destination for young women, these six shows have clearly contributed to strengthening our schedule and our brand identity," entertainment president Dawn Ostroff said.
Still left to consider is freshman show "Privileged." And less likely to make a come back are "Reaper", "The Game" and "Everybody Hates Chris."

Reaper stands just as much a chance - if not more - of renewal as Privileged does. At least Reaper opens up the CW's demographics, whereas Privileged is just another in the 90210/GossipGirl/MelrosePlace/OneTreeHill/etcetc vein.
