The industry has been trying to introduce motion control for over a decade, it won't take long before someone gets it right.
this is assuming anyone can get it right. I think as long as it's dependent on a TV motion controls can not match a real controller...and because of space constraints motion controls can never become the mainstream. as human society grows we're living closer and closer together in smaller and smaller spaces, the majority of people can't dedicate a whole room to motion based gaming like you would need in order to truly perfect it(a very large room at that...). and even then there are some things that a controller or mouse + keyboard are just blatantly better at. just because some industry suits keep trying to shove it down our throats doesn't mean people want it
