Probably not in our lifetime at current pace
Jokes aside, this game has been through many ups and downs (mostly downs). Sierra, one of the original member of the dev team and main writer, quit midway. Nomo, the main guy behind this project, had real life issues. The dev team has struggled and still seems to be struggling to get their act together, so the updates have been very slow.
IMO this game will take another 3-5 years to be completed, although 5-10 years is more realistic. The worst case scenario - they'll just milk it as long as possible and then abandon it.
