also I think its funny how you did not mention in the OP that R* pretty much confirmed in the form of PR talk that Story Mode DLC will not release anytime soon, if at all.
Rockstar said they're currently working on online. That video in which Fonteno says they're working on the DLC was uploaded 9 months ago. They had all that time to work on the DLC.
The DLC could be finished already.
So you are implying SP DLC is finished, and Rockstar decided for no apparent reason to not release it?
Seems logical...honestly for R* it does.
But why would they do that?
Are you sure fonteno wasn't just lieng when he said that, or maybe Story DLC had been cancelled, or maybe they needed Franklins voice over for a previous iteration of Heists, which had been scrapped afterwards.
Also I just noticed I think my Heists theory might actualy be true, since he only says DLC he does not say Singleplayer DLC.
So I could imagine Franklin beeing someone giving missions in the Heists aswell, but it was cut because it did not live up to their standards.
OR they recorded the voice lines for some upcoming Online DLC in which Franklin will be involved which is unlikely, since R* confirmed no new Heists will release and that they want to create new complex game modes, and apartment customization next.
