MMmmyeah, sorry, I like seeing Bob this excited for something but I'm not feeling it. "The future"? Don't you think you're exaggerating a little? To me, continuity is either a cheap gimmick or an impenetrable barrier to entry, depending on how long it's been going. Especially with mashing universes, it just seems like the writers are toying with their own creations, not considering them seriously.
Also, I don't like how studios might handle this - dozens of movies could be shoehorned into the same continuity, purely for cross-promotion purposes, thereby limiting what the writer and director even further. Or, if it's an empty crossover, like the medieval-looking armour or chakram-thrower from Amalur in Mass Effect 3, it makes no sense, it's dubiously crammed into canon, it strains disbelief and wasn't needed.
It's also exhausting. Even with book series, for example, I don't think I'll have the time or willpower in my entire lifespan to enjoy more than... five of them. Potter's already taken a decade off of me, and I'm only starting with Vorkosigan, so regardless of their quality, I'm retching at the sight of any other long-running series.
I think it would also make me risk-averse - if I know something is supposed to run for years, why would I start watching immediately? I don't know if it's any good, I don't want to invest in something long-running if the attention I can give to such works is a limited resource, so I'd rather wait for it to reach a conclusion before diving in. I know a lot of people that avoid series until they have at least a season's worth of episodes - and while TV shows may profit from DVD sales and streaming, movies can't afford to have people miss the box office.
