Good Question:

I look back on when I started hunting 1995/1996. The one thing I wouldn't use today would be non-fiber optic sights. I remember painting my pins with fluorescent orange, yellow and red paint. Brass pins that must have been 1/32-1/16 of an inch wide. LOL

I would like to see in the next 10 years, a replacement product for the range finder. Maybe glasses that wherever you looked, gave you a yardage. That would be sweet.
