Given that it's Google, I wonder if it will support the languages favored by bootstrappers and small startups—Obj C, Ruby, JavaScript and more recently Swift and Elixir. I get the distinct impression that they're heavily optimizing large team productivity and aren't a fan of functional or highly expressive languages.
It's too bad, given how much nicer their app approval process, etc is than Apple's that the Android dev experience has been so much worse all these years.
