Indeed, the best one can do is watch this projected with bated breath... That it develops smoothly and not become another game that gets far more ambitious or complicated over time to extend development to milk their patreons of their money.
Always great to have a roadmap or something of development, but we will have to see if they stay true to their roadmap. Any reworks, "odd delays", and whatnot should be seen with a healthy amount of cynicism.
