Nice info confirming what I thougt. Bought the lifetime pass few days ago after researching the long term plans for the game overall. The vision is immense and I'd like to support it. Assuming all future content is equal or better quality than the base ED game I think it'll create a game that breaks all records for longevity.
With a thriving universe full of extreme details including planet-side exploration / hunting / (hopefully player constructionat some point!?) this thing will probably go for decades being the go-to alternate universe for people to relax and have fun.
