OK, I just had thought. Imagine a wavebird controller, but the whole battery pack area is replaced with a large slot for the rev. controller to slot into. For those of you with the wavebird, you should be able to see what i mean. Looking at the size of the Rev. controller, it could quite easily slot into a wavebird style controller, and be perfectly safe. The power and rumble, and gyro feature would be provided byt the Rev. controller, and the traditional style face button layout would be provided by the add-on. All you would see of the rev. controller is the top poking out, which would still provide you with the power button for example. IMO, this is perfect for people who don't want to follow the new approach with classic style games. Also a dock similar to those with iPod would work perfectly for recharge, and it would look cool too.
