They haven't even released additional modes yet, there's a middle ground between your two scenarios, seems more like they had no real post release plan, outside of a couple things, like the new weapon, new character and Battlepass and have been caught of guard by the insane instant success (not too surprising given just how insane it was and them working on a AAA Star Wars game). They don't have to match EPIC's pace for updates to keep people happy, sure some would complain that they aren't, but the current pace just leaves the game lacking and stale.
Their communication hasn't been great either, which plays into the whole doom and gloom attitude surrounding the game at the moment, like if season 2 starts with a massive update that adds a whole lot of wanted features, I'm sure plenty will quickly and happily jump back on, forgetting the drought.
