Isn't that what you get already in many phones. I didn't think they gave a very strong rumble effect. They look very cheap to say the least and efficient but they really don't look very powerful. I've not used a joy-con though. They certainly look like something that would be much cheaper than rumble motors not more expensive. Xbox one controller has 2 large main rumble motors plus 2 trigger rumble motors. The effect can be brilliant. It's hard to imagine these joy-cons could get close to that. It will be funny if Nintendo have outdone Microsoft with such a low cost efficient alternative.
