Wii Sports 2 confirmed ?

Iwata:

"Isn't that where the Jogging activity, in which you jog with the Wii
Remote in your pocket, came from?"

Miyamoto:

"That's right. I thought it was pretty good fun. As we didn't know if
there was going to be a Wii Sports 2 at the time or not, I gave the
director a call and said to him, "This idea's really good, and since
there's no official word on Wii Sports 2, could we have it for Wii
Fit?" (laughs) Then I told the Wii Fit staff "I know it's a little
late in the project, but put this in too", and the Aerobic Exercises
selection finally started to meet our standards."
