The problem with the hare & the tortoise metaphor is that the hare took a break. This metaphor came into place with the PS360 generation because M$ (being the hare in this case) was winning the race, and then decided to take a break under the assumption that they couldn't be beaten, whereas Sony (the tortoise) did not stop. Instead they continued to move, gaining the momentum to eventually win. Sony (now the hare) will most likely not take a break. They never did when they were the hare in the past. M$ isn't going to win if Sony has anything to say.
