Nintendo 3DS to feature 3D analogue control stick, vibration pack, parallax LCD screens

Following the shock revelation this morning that Nintendo is planning to unveil a 3D model of the DS at E3 this June, more details have trickled out from Japan.

First, tech site Nikkei and the newspaper Yomiuri Shimbun report that the 3D technology comes in the form of something called a 'parallax barrier LCD', as seen in some 3D TVs, which explodes our earlier suggestion that it'll use motion-tracking technology.

Next, Nikkei tells us that it's going to have a '3D control stick'. The exact nature of this implement is unclear, but it could be an analogue stuck, or something else entirely - I'm not sure how a control stick can be '3D'. Nikkei also writes that the 3DS will feature rumble technology.

Finally, the screens are going to be less than four inches in diameter, making it smaller than the whopping DSi XL but bigger than the original DS Lite, depending on how much smaller than four inches it turns out to be.
