It's unknown if the contract simply expires on that date and just needs to be renewed, or if WB is pulling the plug.
It's possible WB could be coming up with their own digital streaming service, such as they did with HBO Go, which launches this Spring for $15 a month.
Maybe the WB/CN shows will now be found on HBO Go?
Cosmic Book News questioned WB about it and is currently waiting a response back. We'll update with more when it's available.
In the meantime, you may want to get watching your favorite shows listed above.
