On the flip side, veteran comedy "All of Us" won't be returning for a fifth season while "Veronica Mars" is drifting towards cancellation as well.

As for its 2007-2008 freshman class, the netlet has confirmed three dramas - Josh Schwartz's "Gossip Girl," the Kevin Smith-helmed "Reaper" and U.K. import "Wild at Heart" - as well as one comedy - "Aliens in America," now a co-production of Warner Bros.
