Does Dual Pixel AF influence lens design? Will all future lenses have STM rather than USM motors?

While all of our EF lenses are compatible with cameras that use Dual Pixel AF, now that DSLRs have movie technology it is more important to have a smoother and quieter focus movement when shooting video. So we developed the STM motor. But this is not a replacement for the USM. Our thinking is that we want to have a variety of motors with different characteristics so we can use the most ideal technology for the design proposed, and for its intended use. Having said that, USM lenses can of course be used
