If they planned a second season from the start, and if they get the time and resources to do it right, I'd love to see it.
But the thing about first seasons/albums/films/etc. is that the official production time isn't really the production time. The real production time includes the entire life of the artist(s) up to the official beginning of production, accumulating ideas and refining them over years and years. If they don't plan a second installment, they pump all their ideas into the first one. If they get commissioned for the second, now they have a compressed timeframe in which to try to repeat a lifetime spent crafting their magnum opus.
