I think story-wise these things needed to happen:

• The Harvey Dent Act had to have a real effect on Gotham's crime rate.

• Harvey Dent himself had to become a legend.

• The Batman's own legend had to fade away.

• Talia al Ghul had become old enough to be part of the story.

Whether 4 years would've been enough for all this to happen is debatable IMO, especially for the first part. Laws take a long time to have noticeable effects. So 8 years seemed reasonable to me.
