Is Offset Finishing R&D Finished?

I get to see a lot press rooms and binderies. And I can see the mix of digital and offset gear, sometimes sitting side-by-side. I often wonder if we've seen the last days of offset press development and innovation. After all, how much more efficient can we make the technology? And the same applies to the finishing end. The "golden days " of high-speed finishing systems were really in the mid-to-late 90's and early 2000's.
