I think we will start to see a time period when bow designs will again come back together to be more similar. Whether it is the limb design, riser geometry, cam design, etc.. I think for a time that almost all of the companies will have extremely similar models. That will last for a brief time before someone comes out with something truly revolutionary and we will again have the diversity that we have now.
I am also sure that newer materials will also make bow designs more durable and more efficient.
And lastly, ofcourse, prices will continue to increase.
