The new Nintendo 3DS could come complete with rumble features if a newly discovered patent is anything to go by.
The patent itself doesn't mention the DS or Nintendo specifically, but talks about a "vibrating motor" in a Japanese "foldable hand held device".
If it weren't for the accompanying image with the patent, we'd think this was something related to an entirely different pastime.
Check out the images below though and there's little doubt that we're talking about gaming here.
This comes amongst quite a buzz surrounding the DS series after Nintendo announced the 3DS earlier in the year.
