I was reading an article by the guy who runs kryptonsite.com, and it included this-
"The Superman Homepage [website] says the producers are 'attempting to close a deal with Michael Rosenbaum to return as Lex Luthor, wanting to sign him up for at least 9 or 10 episodes.'"
It's also mentioned that the absense of any renewal news is due to a delay in working out contracts and such, that otherwise insiders say things look very good for a 10th season, which I'd say the above quote suggests anyway.
