I agree, it does get rather convoluted if you try and map things out, but I don't think there is too much stuff in the trilogy that's self-contradictory. I meant 'consistency' in terms of the 'tone' or 'feel' of the finished product, even if the 'new perspective' may have a different tone.
That's exactly my idea of consistency too, anyone who has seen Terminator 2 or Robocop 2 and then has seen the 3rd film will know what we're talking about.
