I really wonder if WB/DC can do the service and actually get the CW stuff on there quickly.And they need to be on that new service they are launching instead of CW seed.
I can definitely see WB being okay with them doing it but I don't think CBS would want their stuff going to an exclusive WB platform quickly.
The DC service would be a great deal if you could get

Flash
