It is probably still subject to change (as was the last...sigh) but the Mozilla Firefox browser road map says 1.0PR is due out today. 1.0PR will be followed by 2.0PR and then RC-1, 2, and so forth until 1.0 Gold comes out (scheduled for October 11th).
As noted, the schedule has already slipped at least once and will probably slip again but all we can do is watch as they move closer to going gold.
