Obviously, it has a widescreen e-ink screen (320*180, black/white) for in-controller XMB to change things like Invert Y axis, enable/disable rumble, assign the controller, set timer to shut down, calibration, etc. It would have to have some internal memory to store settings and it's upgradeable firmware.
The buttons underneath the screen are for multimedia. Previous track, Play/Pause, Next Track, bring up Buddy list, bring up unread messages, bring up controller settings. (something PS3's should have had)
The bottom line of the screen shows custom soundtrack info (play state, scrolling song name, current position/time remaining, and duration). This screen would also be used in game for text chat (so more of the conversation can fit on screen) or games could use it as a screen like Dreamcast's VMS. Games can choose to hide the status bars or not. It could also have little minigames like the VMS/PocketStation did, stored in internal memory (hopefully even PocketStation 1 games). You could set all XMB notifications (Buddy signed on/off, new trophy, error messages, etc) to show up on the controller instead of the TV (along with an accompanying noise to tell you to look at the TV)
It would have a speaker for said noises. Either just beeps, or like the Wiimote. Doesn't really matter. I guess a full speaker would be more useful.
Instead of the internal battery, the battery would clip into the back. Sort of like how a battery cover clips onto the back of a remote or GBA. Only the battery would be it's own cover. (something PS3's controller should have had)
In between the 2 analog sticks is a normal-sized (master) USB port. You can plug specific USB devices into it (microphone headsets, keyboards, mice, etc) and the controller would act as a hub to the console.
Beside the USB mini-B charge port is a microphone headset port like XBOX360's controller (something PS3's controller should have had)
It would use Gamecube-style, wide/clickable analog triggers. (The best triggers of any controller IMO)
I forgot to include it in the drawing, but it would have wings that are longer than Dualshock's, like the original SCPH-1150/1180 Dual Analog controller had.
And the one feature I've wanted for years, the only thing that would have actually made the Wii stand up to the code name "Revolution". Directional Force-feedback. There would be a spinning 3 axis gyroscope (2 would just point the third, the third would spin whenever force is to be applied) which would let the controller push itself in any direction. (Sony can call this feature TripleShock)
It would still have DualShock 3's features like charging over USB, rumble, SIXAXIS motion detection, bluetooth. However it's battery life would obviously be shorter unless they used a bigger battery of course. And it'd probably cost almost twice as much.
I call the controller, PocketStation 2.
The concept is taken from the dreamcast and it will help when playing with your friend in sports games like Fifa,Madden,etc.The design could be modified as it is only for showing the features of the controller of my dreams
