In Telltale Batman, Bruce Wayne's Father was revealed to be Corrupt. I'm thinking this Film might go the Telltale Route. Just an Educated Guess.
Yeah it does feel like they took a lot of inspiration from the Telltale games for The Batman. Serial Killer Riddler, lying Alfred and the Batman and Catwoman relationship front and centre.
Your prediction seems right-- but with a twist that Catwoman is really working for Riddler because they are friends! :P
