The comic book fan base seems a bit future-shocked by this development; they're wondering what will happen to the traditional ways of finding and enjoying comics at stores (both new and used).
SF fans, on the other hand, have been expecting this development since the mid-1960's. In his 1965 novel The Zap Gun, Philip K. Dick wrote about battery-powered 3D comic books:
Before him lay the October 2003 copy of the uncivilized comic book, The Blue Cephalopod Man From Titan. At the moment, his lips moving, he examined the entertaining adventure, The Blue Cephalopod Man Meets the Fiendish Dirt-Thing That Bored to the Surface of Io After Two Billion Years Asleep in the Depths!
... winking on and off, on and off ... and would continue to do so until the five-year battery-plate contained within the back cover of the mag at last gave out.
