Guess whats gonna be in Star Trek: Discovery that, by accident or design, contradicts something established in previous Trek adventures. Winners get no-prizes. I'll go first: I expect the technology of the USS Discovery NCC-1031 to be extrapolated from what we have today, which is far ahead of much of what they imagined on Kirk's old Enterprise. Wireless technology, animated touchscreens, holograms, a computer voice that speaks normally without typewriter noises. It will not conform to what we see on the USS Enterprise in "The Cage" I also expect them to have/learn much more knowledge of Klingons and their culture (which I expect to be TNG-based) than was apparent in Kirk's time.
