I actually think this news is worrying.
I dont think many people that play on handhelds in trains & busses, do it with other players, or want to do so.
I cant imagine it being any better than its motion controllers.
People on trains&busses dont want to take up too much space, or swing their arms around.
And you know someone is gonna try playing even on a crowded train/bus, and accidently hit someone because of this.
