NEVER say never lol! Who would of thought even 15 years ago that 300fps hunting bows would become the norm? Who would have seen the invasion of carbon arrows and mechanical heads? Fibre optic sights, drop away rests. Carbon fibre and magnesium. If need is the mother of invention, then technology must be the father.
Look at compounds of 20 years ago and look at them 10 years ago, 5 years ago, todays models and what a few mfgrs have " developing in the wings" . I think a close parallel between the " super mags/short mags" and the smaller lightweight speedbows of today is simply a function of our desire to have a day in, day out " 500 yard deer rifle" or a " 45 yard hunting bow" . Technology has given us this and our desires continue to evolve as does the sport itself.
With things like biological/mgmt advancements and " trophy production" being an option for practically any area of the country now, I dont see any decrease in the demands for better and better equipment. Whose to say there wont be a replacement in 10 years for carbon arrows? What about replacement of stainless steel/aluminum broadheads? Conceivably their IS a possibility for a 50grain broadhead on a 200 grain shaft to be fired at 500+fps (or even considerably more) that would TOTALLY redefine what is a " longshot" for bowhunting. There are 400+fps bows in a few mfgrs R&D labs as we speak and have been so for awhile. If they are ever built affordably and realiably you can bet that the target and 3D guys will be the first to bring them to the public eye!
Dont forget the demand for " small" bows (under 45#s) for realistic big game hunting use will totally change the marketplace. Kids, women, handicapped and small guys will FLOCK to the archery sport when common and affordable options are given. And this will likewise require laws to be changed in many states. So its just gonna take time and is in the future of the sport. The more numbers we can get involved the stronger we will ALL be!

The future is breathtaking and inspiring in some aspects and our sport is one of those parts of the future that will keep me guessing and going!
