My initial reaction to hearing 2.0 is that this is basically a different
name for Disney Infinity 2,
instead of using a catchy tag line like Giants or Skylanders, or even just using a simple 2 or just adding a year to the title (it works for all the sports titles like WWE or NFL), they look to have decided to go down the edition number way which sounds
odd but I think it actually makes things a little more simple.
One of the Hockey Stick team and RealClimate.org organizers
named Rahmstrof used a very
odd mathematical alternative curve shape
instead of just fitting a curve to his data.
