I believe companies will continue to improve in the efficiency department. I'd like to see a bow break the 90% efficiency barrier. This will mean more speed, quieter, and less hand shock.

Some non-standard bows will come out (Sims bow). I've seen the patent drawings for that bow and it is strange (no externally visible limbs or cams). Bow companies like Monster bows may see a jump in interest.

I'm sure the speed bow club will be satisfied with even speedier bows next year as well. I don't know that the 400 fps goal will be reached, but I could see bows in the 375 fps range.

There will be something for everyone.
