In terms of innovations, we haven't really seen anything that could improve the sport as a whole. In my opinion, looking at the technologies behind marker manufacture won't hold any keys to a sport-wide revolution, it'll just breed the next generation of "isn't my gun special" consumers. Sure, innovation is nice, but I think making the sport more affordable and accessable is a much more fundamental goal than producing, say, a marker without a macroline.
Like I've said, innovation doesn't equal success. What PE have done is produce workhorse reliability on a tournament grade marker. You get new guys getting into it asking advice on what markers to get, you either point them in the direction of the cheaper budget markers (slg, ION), or second hand ego's/eteks. They still keep up. They're simple, functional, and they've stood the test of time.
Yes, PE use already existing technologies, but they use it to produce quality markers. Just because they're not at the forefront of research doesn't mean they're not a viable company producing viable products.
And besides. There will always be companies that come out with the next big innovation. I seem to remember there being an ego7, ego8 and ego9 but we still have the wonders of rechargable, macroline-less, usb fitted gats. Don't fret too much.
