I can’t give you a date on 1.0, but what I can say is that the team has been very considerate in planning for upgradeability. Based on past experiences, I wouldn’t hesitate to use MODx on a commercial product (as many of us have and continue to do). Upgrades have not been too messy in the past and I don’t see any reason why that would change.

I could be totally wrong.
You think you’re impatient? I keep chewing up mouse cords.... Third mouse this week. I have written a script that sets off my house alarm if the numerals 1.0 come accross my rss feed.
