From a Gamespot interview sourced here - http://dualshockers.com/2010/02/project-needlemouse-unveiled-sonic-is-back/
GS: Will there be any differences between the different versions? That is, will the Wii have motion control, or will the PS3 and 360 run at 1080p?
KB: For all intents and purposes, the games are designed to be identical. There are a few differences per what each console can output visually: Wii will be at 480p, while the XBLA and PSN versions will run at 1080p. However, for certain areas of the game, the Wii will be able to use motion control, and the PS3 will be able to use the Sixaxis.
--- Dk if it was ever confirmed but i guess it is now.
“When we make some new announcement and if there is no positive initial reaction from the market, I try to think of it as a good sign because that can be interpreted as people reacting to something groundbreaking. ...if the employees were always minding themselves to do whatever the market is requiring at any moment, and if they were always focusing on something we can sell right now for the short term, it would be very limiting. We are trying to think outside the box.” - Satoru Iwata - This is why corporate multinationals will never truly understand, or risk doing, what Nintendo does.
