In fact, I believe that all four of Clarke's 2001 novels (2001, 2010, 2061, 3001) are set in slightly different 'universes'. He even admits this in at least one of the forewords.
Yeah, I think he refers to them as "variations on a theme" in the foreword to 3001. Sensible approach. I think that it's one that could easily have been taken with the new movie without tying it to existing continuity. Tweak what it makes sense to tweak, but keep as much of the important stuff intact as you can.
