The most interesting thing will happen when an Android phone with a screen & keyboard is Android with a Chrome desktop. Marketing shouldn't be burning the midnight oil to figure out the branding of Android/Chrome cross overs.
If Google were to release Chromium OS community builds for Nexus phones, I'd have a gander. (My Nexus 4 needs a new battery and I don't have the spare change to run out and purchase a Pixel!)
HTML5 for the phone and Android/Crouton compatibility via Wayland would make for a nice challenger to Ubuntu Convergence/MS Continuum.
