Something just occured to me, had to let it all out before going to bed.
Nintendo's philosophy has become one of bringing gaming to the masses. But they ran into an issue with the wii, hardcore gamers felt alienated.
So how do they maintain and even further expand the blue ocean philosophy of the wii and motion controls, yet win back the hardcore gamer?
Look at the codename, and combine it with the few hints we have.
Cafe? A cafe is a place you go to have a caffeinated drink, or milkshake etc with a few friends. It's an open, public place, it brings you outside into the world.
So we have a controller, that has some sort of touch sensitive display, the touch feedback ain't too fancy, but apparently the controller itself is multipurpose.
So it got me thinking. What if it's a segmented controller with a flexible display, and what if you wear it when you go out for a drink with friends? What if it's not meant to be a handheld semi-console you take with you out of the house, but something you actually put on and wear? Maybe around your arm?
Both hardcore and casual hip all at once.
