Why are so many people not even mentioning this feature? It sounds very cool, and hands on experiences with it have been very positive. It's definitely the next step in rumble tech. For the low amount of raw power that Nintendo systems have, their "gimmicks" (hate calling them that) are usually pretty cool and work pretty well. 

It will certainly make the girl gamers very happy

Its probably cause we don't even know what software will support it........ I want to feel getting inked in Splatoon!

But I feel likes its going to have the same effect as the "3D" on the 3DS! 

you can tell if it has one, two or three ice cubes in it!!!!!!

Haha, that's gonna be the next "my body is ready"

Laura Kate Dale, had a hands on with it. She said it was a really awesome feature, she said it actually felt like there was a marble in the controller.

I guess nobody is talking about it, cause it's hard to get excited about without hands on experience. But, by 2020 it will be a standard feature of controllers.

Mainly cause it is a feature we can't gauge as it is purely tactile. So we willhave to wait to see what various hands on impressions say to even get an idea of what it is like

Do people not realise it's in the Ds4?
