As soon as Nintendo launched the Nintendo DS, with its "Touch!" campaign, it was only a matter of time before DS games with touching were released. Japan saw a spate of boob-jiggling titles, such as Doki Doki Majo Shinpan.
Picking up where the DS left off, the 3DS is already getting "touchable" jubblies with Senran Kagura - in 3D nonetheless!
The Wii U will no doubt see an array of titles that make "inventive" use of the Wii U Controller. Nothing explicit - that wouldn't get the OK for release - but rather, questionable.
