Dave Smith talked out this in his recent interview. Made a few interesting comments that I hope I haven't misheard/mis-interpreted.
-Will take place at the end of this year and follow through to 2015 (already known but it's good to know nothing has changed).
-The review will be "A long, hard, cold look at the structures that we've got ... and make an assessment of what we want the game to look like in the next 10-20 years".
-Expansion not necessarily being about moving from 16 to 18 teams.
-Talked about how important it is to focus on the regional and international element of the comp
-Importance of stadiums, infrastructure, urbanisation(growth trends), participation, pathways and structures, etc.
It really seems like he's passionate on getting the existing clubs up to speed rather than over-expanding like we did back in the SL era and how the AFL, S15 and A-League have since then.
Again, I may have mis-interpreted some comments as this was only a small part of the interview so don't take it as fact.
