Code Complete means that the work is mostly done on Mozilla side on this release (we still fix/backport some blockers that are found late in the testing cycle).
Then OEMs have their own shipping schedule so it takes some time before you end up with devices sold or updated to this release.
Is Code Complete the planned or actual date when Firefox OS reaches this stage? I didn't see any news regarding 2.0 around September, 1.
Is the release model significantly different from Android, where Google publicly announces the release of each version, even if it will still take some time for phone manufacturers to incorporate this version into their releases?
