This increases the possibility of HTC Zoes and Highlights coming to the Google Play Edition HTC One. Given Google’s promise of updating these devices quickly however, they might come in the form of apps rather than integrated within the operating system. But since the kernel is handled by HTC and not Google, it’s anyone’s guess.
My bet is that someone in the Android community will release a device specific app for the Play Edition One to enable those two features. HTC would rather you buy their version with Sense, so I doubt they’ll provide the app themselves. Regardless this is a new breed of Android smartphone and we’ll only know the how it “behaves” over time.
