The Chrome and Android teams don't seem to be great bedfellows, it seems - it isn't clear to me what demarcates Chrome-branded products from products running Android in areas far from their original targets.
The GoogleTV g+, twitter etc. feeds, previously pretty active, have been dead since January. My guess is the bulk of the GoogleTV engineering talent left it to make chromecast.
Chrome is likely the right name here, it supports most platforms where Chrome runs, not just Android.
