For anyone who is interested, the current progress for 0.9 is shown as 29% on Subscribestar. Based on the timing of previous releases, my guess would be an August/September release.
No, I believe Caribdis has said that the story would end at Version 1.2 or 1.3. So we're still a couple years from the end.
I'd say the final version, based on the rate of releases, will probably end up being released sometime between late 2026 - mid 2027. (Do note that this is pure speculation, I'm just basing this on the rate of updates)
