2014 Macbooks

So what do you guys think the next macbooks will feature? The current design has been applied to several models already, not to mention that other laptops are copying off the macbook's design. What about display screen? Apple is already pretty close to 4k with the current models of the pro, do you think Apple will bump it to full 4k resolution? How about touch screen or air gestures ala leap motion technology? Apple has acquire Primesense so lets see how they use it. Me personally, I am hoping Apple adds all of the above. Also I would love to see Apple bring back the black Macbooks(why did they discontinue they anyway?) I am looking into getting the next gen Macbook pro as I want to begin iOS development. What other features do you guys want to see for next year?
