Give me a Nexus 8 or a Second Gen Nexus 7 and I'll be happy. I don't expect a new Nexus 10, a Nexus 5, or any other hardware. But I would love to see a new Android tablet in my price range.
Also, don't expect the X Phone. Google already said they are not going to focus on hardware. So also throw out a Google Watch, it won't happen.
Android 4.3 sounds like a minor update. I would like to see what Google did to Android fluidity happen to Android battery life. I think I heard a rumor of Project RoadRunner. But who knows. Other than that, 4.2 added no features that I actually use day to day. Unfortunately I think it is realistic to expect that 4.3 will be the same. Which is sort of a bummer. Of course you can't always come out with something amazing. But it is still good to see companies at least try to push themselves.
New OS features I want:
Better battery life
Integrated video chat
Proper cloud backup. (I had to restore my old iPhone from an iCloud backup the other day and it worked flawlessly. Restored all my data, apps, and home screens. Worked all in the background and I could use it while it was restoring. And from my internet, didn't take longer than 30 minutes. I know it is cliche, but it really did just work.)
Make Chrome as fluid as Safari on iOS
Make Google Maps work as fluid as on iOS. No more splitting up directions and navigation. Who ever thought of that was an idiot.
Google Now improvements. It is really just voice search. There are so many things Siri can do that Google Now can't.
Of course adding all those things would be a major improvement in my eyes, earning a 5.0, not 4.3.
It will be a new Nexus 8/Second Gen Nexus 7 along with Android 4.3. Everything else that will be talked about will be geared towards developers. That is my prediction.

Oh I see. Interesting. What's the difference between chrome and chrome beta at this point? I'm just using beta.
As for Google voice it crashes on me sometimes. Also it doesn't load when you have no service (not necessarily a bug). Wish it would let us open it at least even without service. It's also just slow sometimes. Again, I love the app but it could use some tidying up.
Most Google apps could use some serious tidying up.
