I kinda think the technology leader would be the one who's doing the technology I like. And that would be BowTech, specifically the center pivot limb design.
Frankly, there isn't much room for 'innovation' that hasn't been tried before. Single cams had been around long before Mathews, for instance. Mathews is using old Bear technology like the roller guide and string stops. Hoyt is using old Darton cams on a spin-off of an old Martin riser. Even the hot 'new' parallel limb designs harken back to the old 34" a-t-abow from Rigid in the 70's.
The old designs usually didn't work with the materials available at the time, or were ideas that archers of the day looked at and called 'BS' on 'em. Now we have improved materials that make those old innovations feasible.Also there isa younger generation of shooters that don't remember those old designs, have a thirst for stuff that's new and different and aren't so careful with how they spend their money as the old timers were. So the companies can recycle the old ideas with new materials and market them as fresh new innovations. They make money, the shooters have their new toys and everybody's happy.
All the while there is someone sitting back, thinking to themselves... SUCKERS! [8D]
