My guess is "always next Tuesday"
These Open projects often go on for years before the reach the "commercial" world.
I mean what.. it's only taken Wine like 15 years to get to version 1.0
Android has been going on for years. It existed before Google bought it.
Open source should take less time to develop than closed because more people can work on it and bug testing is a shorter phase. However a hobby venture (like wine) takes longer than a commercial venture (like Adobe or Android).
Wine's time line is pretty sad. But even still Wine has been a useful and far superior product to most commercial releases.
