I have a feeling they will add more and more Android device APIs to whatever is coming, until it has just as many as the Java APIs.
I've thought for the past year or so that there is no way the future of Android app development is Java/Dalvik.
It's possible they will add support for other languages besides Java. Android is stuck with Java 6, which sucks...
I am not a web developer BTW, I am primarily an iOS dev who has done ~6 months of Android work.
I think that Java 8 is a great language, I like it a lot more than Javascript. Go would be great too.
As-is, native code on Android is a cluster, and even for games it's pretty uncomfortable and filled with Java shims. Kinda gross.
Frankly, I'd trade Java for Go any day.
I'd love to see Go on Android. I doubt it will happen anytime soon though because it would require an entirely new runtime library environment to really be Go-like, just bridging Go to the existing Android Java APIs via Java<->JNI<->CGO<->Go would result in something very horrible.
Internal restructuring like, say, Andy Rubin beyond deposed as head of Android and replaced by the guy in charge of Chrome (Sundar Pichai), who now oversees both Chrome and Android? Because that happened in March.
(Chrome is the default browser in nexus devices. Whether it's the default in non-nexus devices is up to the manufacturer & carrier, who usually choose to use the AOSP browser - an unbranded front end of the system webkit - because they can control and customise it, which they obviously can't with chrome as a branded google app that's updated through the play store).
