Higher resolutions, especially for tablets. For example iPad 4 has only now gotten enough GPU performance to be as fast as iPad 2 running at its old native resolution. So iPad 4 at 2048x1536 is as fast as iPad 2 at 1024x768.
So basically the iPad has stagnated for a year and a half in performance, just to get the benefit of that crisper display. And only with new upcoming chips, the iPad will start to get higher performance for native-resolution apps.
However, about speech recognition for instance, it is for now done "in the cloud": your recorded voice is sent to a server which does the intensive computations and sends the corresponding text back to your phone. Why would that change? It even allows Google or Apple to train their speech recognition system so I think they will want to keep it that way.
More generally, more and more computation are done in the cloud, even on the desktop (Chrome OS).
That said, I agree about high-res gaming and augmented reality, etc.
