How will controllers evolve?

It shocking to see how quickly controlers evolve. It seems like around every 2 years companies trump themselves. Looking at the current offerings, aside from changing material and rearranging, layouts, input/outputs It seems like things are at a height…but technology is ever evolving.

What new controllers do you expect for 2014 and how much better can they get?

A wireless one with lesser buttons and more functions perhaps.
