^^ I don't think it's a problem. Most people probably don't realize this, but Star Citizen's funding has actually been surprisingly consistent.
From Sept 29 - Sept 29th, their income each year has been....
2013 - '14 = $34,846,602
2014 - '15 = $34,314,957
2015 - '16 = $34,921,429
I don't think any of this is by accident, I think it is by design. I think Star Citizen's spaceship sales are carefully planned out to meet this number each year. All this is possible because ships in Star Citizen only go on sale in limited quantities for limited periods of time. They actually have quite a bit of control over their income.
On top of this, I think Chris Roberts will keep developing this game until it meets his expectations or runs out of funding. Honestly, I think that's what his fans want him to do. They were promised a game that would push the limits of PC gaming, and that's what they expect to receive.
