Blizzard just released a new patch for d3 adding "Paragon Levels" which there will be 100 of, level 1 will take just as long as 59-60 did so it will be a pretty long grind. Each paragon level you will get 3 points to your primary stat, 1 to the others, except vitality in which you will receive 2. Additionally you will receive 3% mf/gf per level. Also there will be certain effects added to your character at designated paragon bench marks.
Gonna try it out
