Will KitKat bring a new design?

So, just about everyone here knows about the recent announcement of android 4.4 KikKat. What surprised me was that it was android 4.4, and not 5.0. This got me thinking about how many new features Google will actually pack into this update. The last few upgrades have only been incremental upgrades, with very few new features. But Google did change the name on this upgrade, so that has to account for something, right? It's just that the stock tron themed ui is getting a little stale and boring, and I want a brand new lighter card ui. Do you guys think that 4.4 will pack a bunch of new features and a new design, or will it just be another small update?
