Allow me to make a stretch, if you will.
Sony revealed their new controller, the Playstation Move at the Game Developer Conference not too long ago.

It is similar in function to the remotes the Nintendo Wii, but utilize a 3 Axis Gyroscope and a 3 Axis Accelerometer with higher sensitivity to the Wii controller. The Move controller works in partnership with a camera system (Playstation Eye) and a colored globe that is at the end of the controller. The combination of the MEMS control and the optics system provides a perceived faster response (sub 1 frame of latency) than the Wii motion plus, but with the same feedback and accuracy.

According to SilliconEra, the Square Enix Group is on the list of “developers and publishers that would be supporting their “Move” peripheral. ”

What does that mean for the future of the Kingdom Hearts games? Does this mean that we will have the option to use this new controller and actually swing keyblades and sticks instead of button mashing? Nothing has been announced yet, but the trailer for the controller does plant seeds of hope in me. Check it out:

Again, this is all speculation, but it would be wonderful if it were true.
