It'll probably be 3 years or maybe more before the Persistent Universe actually feels like a 'whole' universe rather than a bunch of instances of different modules stitched together.
But along the way to that point, we'll have 3 single player campaigns with co-op support, Arena Commander 2.0 with full multi crew ship support, and then Arena Commander 3.0 with a capital ship boarding/assault game mode.
Funding charts show they have never actually slowed down in terms of pledges. They're still averaging 3 million a month in pledges even with an only barely playable game so far.
Once the FPS module comes out, I'd expect that number to rise as they start selling cosmetics and shit for FPS characters.
