I don't know about you, but I'm all for high speed transportation. Besides you were able to use the train in the original, you just had to walk there first. It seems they just cut out an extra step.

Also, apparently the games will be hitting Japan store shelves next month, with a reported street date of September 12th. A pedometer will be included, in case it hasn't be mentioned before. What will that device will be used for exactly? I'm not sure.
