The Titans show is basically being funded by their international deals with Netflix. Which in turn pays for the shows and makes them profitable, then they are used to help bring in new subscribers to DCU. So sure it will get a season 2 as long as the service is here at all. Don’t know what kind of numbers DCU gets or what kind they need (CBR and io9 not to diss them are hardly the Wall Street Journal) but I will admit the fact these forums are no bigger then they are is probably not a good sign. I hope not thought because I love this service and do not want it to go away especially this year, but will also admit DC has made mistakes starting out. Would assume something like this was not planning to rake in loads of money right out of the gate, streaming services take time, WWE Network lost money it’s first year too. But DC maty have seen it as a cash grab we don’t know.
I do think the Warner service could be an issue for sure. Honestly if it is going to be more expensive then HBO like some say I frankly don’t want it, I am not spending that much for one streaming service especially a new one. I think there is room for it and DCU to exist (although it would mean the new movies would never come here which is bad, but a site featuring a comic selection and less recent movies and TV shows could co-exist depending of if it could draw in enough.
As for the Gotham and CW shows… those shows have pre-existing streaming deals. DCU is not keeping them off here because they thought we wanted to watch Superboy and Birds of Prey more then The Flash and Arrow. I doubt even if they wanted they could put them on here before 2019 ends without at the very least paying a boat load of money (likely millions) to end the current streaming deals which godo chance Netflix would not want to do anyway.
