So CG just abandoned the "neutral alignment" idea, didn't they.

Some of us were hoping an upcoming GL would be Revan as a neutral GL, but apparently the next GL to come here is a GL Thrawn from Ahsoka season 2. 

They "plan" things out for a certain amount of time and if something doesn't get finished in that timeframe, they just keep moving on for the next release or next project.  New shows and movies can cause a change to that so they can release "new shinies" related to what's just been 3, 6, or 9 months ago.  As you see now with the focus on Ahsoka season 2.
