How big will the sport of cornhole actually get? If it becomes a competitive sport aired on television, what would it be like? Would the rules change at all? How would the sport be organized? I'll give you an idea of what I think the sport will be developed into during the next couple of years.
First of all, I think right now that the American Cornhole Organization (ACO) has a major grip on the sport, and therefore the best chance of bringing it to television. At this stage, I think it all comes down to the money and sponsors. Whatever organizations are able to bring in the most prize money through sponsorships, etc. will end up being the big players in controlling where the game ends up. However, it also depends on the planning and structure that the "pro" players are involved in now. Right now, the ACO is really the only organization that recognizes the best players in the country, and the players seem to like the way the ACO is running things... for the most part.
There are a couple "cracks" in the way things are going right now, but you have to expect that in the development of a entire new sport. So let's say the ACO does become the governing body of the sport and organizes a Pro Tour. Right now they have a lot going for them in terms of developing a way to rank players and have them compete against each other. However, there have been a few complaints about the way tournaments are operated and such. I am certain that all the little problems with the way the rankings and tournaments are structured will be sorted out by the ACO soon because they seem to listen to what the players want.
I believe that the future of competitive bean bags will be similar to the way the ACO does now. Players will earn points in a series of single-elimination tournaments throughout the year, and be ranked based on the points they earn.
