So the big question is: what exactly will KitKat play host to? If it's not going to be the major new overhaul that we all expected of Key Lime Pie (5.0), and it looks like it won't be because this update is still within the 4th iteration of the OS. So if 4.3 wasn't much of an improvement, other than to security, performance etc, then what will we most likely see from 4.4? I think the start of the fragmentation issue will begin being addressed, with 4.4 to roll out to as many devices as possible in anticipation of 5.0. I'd also expect a lot more voice activation/gesture control features in anticipation of the rise of wearable technology. But the fact there will be a 4.4 makes me think the changes will remain relatively minor and it won't be until 5.0 that our socks are blown off.
