So this is kind of an interesting concept that may turn into potential E3 news, seeing that the patent has been filed 2 days ago. Using a special stylus and an attachment to the front camera, it may be possible to equip your 3DS with a fully functional top screen that gives us the ability to manipulate objects in a 3D space. The added bonus is that that stylus may have a built-in rumble function, too. All in all, these are very interesting concepts that may turn into reality at E3 or TGS 2012. Add these features to a right stick and we may see a 3DS revamp that includes everything early next year.
