Will Apple Adopt Gesture Controls To Make Macs Stay Relevant In A Touch Screen Future?

So what will they do, many believe that touchscreens arent useless (http://www.theverge.com/2012/11/30/3710900/gorilla-arm-touchscreen-laptop-windows-8-apple)

and if the chrome pixel is a indication of anything, its that touchscreens are the future.
Now what will apple do to stay relevant i read a long itme ago(2010) that they patents on laser keyboards and stuff like, from what i've seen leap works well on a imac, so why can't apple do something like it, (ergonomics aside)
