Superbot has had a lot of time regardin DLC, hence we get DLC quicker. SSM is starting from scratch. So it'll take longer. And Superbot got easier DLC first, like Kat and Emmet. The more we get, the slimmer the possabilities are in terms of getting simpler DLC, thus making them reach out for harder ones, third party.
Also, if anyone ever pays attention to the blog, there is a PSASBR Heratiage sale. So if people still say that this game is forgotten, it isn't. They're even having this sale in honor of this game. And since it's a big event, it is safe to say that more news will come in the future.
I really should consider being a lawyer when I'm out of High School. People here complain a lot and it's so easy to go against negativity here.
The fact that there is no definite response from SSM means that they probably dont have the time or the money to put in to make more characters. It isnt like superbot, this was their only project whilst SSM have other stuff going on like GOW ascension
SSM have always been working on this game. Even when God of War: A was in development. Granted superbot did most the work up until now but SSM will still support the game apparently. I do agree though I'd be very surprised if we get anymore characters.
