dude!!..you make too many weird assumptions lol.
Leap 3d has hardly got anything do with Sony or PlayStation. Sony already has Move, and theres no way they would ditch it.
I said it can be or something of that magnitude. I didn't say it has to be leap. Besides technologies evolve and thus old ones get ditched for new. Its a huge probability that move tech might not feature in ps4. You never know.
Assumptions look and seem weird sometimes.
