You might want to wait on project Cheddar then - seems like a good solution.
It's a mouse (so you can aim with the mouse), has a thumbstick (you can move with it) and has a lot of buttons as well that you can use for your actions...
No luck for me yet. Mine is a no customization left handed white. Ordered on the 23rd, hopefully it ships soon.
Is there anyone I could tag for any kind of update on this?
