I still think all the buttons and the sticks on the DS3 / six-axis are a step back from what they were on the DS2. Whether that's because of the six-axis motion stuff (seems unlikely) or because of a focus on making the analogue controls non-linear so they're easier to use for "twitch" inputs (like platformers, twin stick and first person shooters etc.) or because of scrimping on that hardware, I don't know. I just hope they get the sticks right this time and actually make them at least optionally linear, because they're awful for throttle control and brake modulation in GT5.
If anything, it's the motion control that was pointless in the six-axis / DS3, and they ought to have made the basic controls better and left out the motion control entirely for Move.
