It was very disturbing to learn that Google will not open source Android 3.0 in timely fashion.
What is the meaning of in timely fashion?
The phrase in timely fashion means quickly, promptly, within a reasonable time frame. One might also hear in a timely manner, which has the same meaning.
Basically, it means "quickly enough" or "on time".
Omitting the article makes it sound a little awkward, but not necessarily incorrect.
