Has State of Origin reached its 'use by' date?

Perhaps just 1 super game per year, winner takes all. Brisbane one year, Sydney the next. Think about it. 3 games per year, split rounds, player burnout. Get rid of 2 SOO games and it could make way for the extra teams the NRL want and also a fairer draw. How many fans out there are lamenting the fact that their team have too many rep players? Should the top teams have to 'budget' 3 losses a year when SOO comes around? Sure, Queenslanders will say 'No way', and NSW will say get rid of it all together. What do you guys think?
