It is simply unrealistic to expect even fans to have endless patience. If nothing substantial happens in the near future the threatening narrative of Star Citizen as a failed project will continue to gain plausibility. The company exploited all kinds of monetization options, I can't think of anything that is left for them to generate more cash. If they would have been successful with finishing the core game they could think about monetizing additional stuff especially by introducing other gameplay options. But with the current development debt this is less and less of an option.
I definitely don't have a clue how long hardcore fans can survive on hope and how big the group of hardcore fans ready to further finance the game is actually. But there will be a point where Star Citizen will even lose the rest of the relevance of its existence through ageing alone. The hype and innovation phase is long over, to me it seems Star Citizen is mostly a depressing cosmos now, no progress since a long time and mostly negative news regarding the court case shedding a bad light on the fundamentals of the project. The videos that the company releases are unwatchable and bore me with the constantly repeated story of "the game will be awesome, we just can't show it to you right now" and a lot of blabla filling the gaps of the story with hot air.
