A new round of rumors from NeoGAF suggests that, the version of the controller that was leaked a few days ago has a screen size that is “slightly bigger” than what we’ve seen in the past. The difference is “less than an inch” though, and even with the increase, “the resolution hasn’t changed”. The screen has not been upgraded to multi-touch, and:
The mysterious small square under the D-PAD, is not a vitality sensor, not even in a light version, not a touchpad, not a mini pulse sensor as on sports equipment, not a decorative thing, or whatever. This is the NFC sensor.
It’s then clarified that:
The demonstration of this feature in the Rayman leaked video isn’t representative of how it will work, such a use could obviously have bad consequences for the screen if people would put figurines briskly on it.
These leaks and mysteries and more are starting to pile up. E3 2012, hurry up. You’re taking too long.
