The 100th anniversary will be a holodeck simulation
Which will piss fans off. "Bah, holodeck's are such a gimmick. I wish this fad would just fade away so we can go back to old-fashion 3-D." "The technology now exists to create realistic simulations of anyone, even dead people, and they still left out the original eight Doctors?" "I am so sick of the damn Daleks, it's just gotten worse since they entered the public domain."
Yeah, I know the last one isn't about holodecks. But I figure fandom will still be bitching about them, well, always.
