Sadly not for other phones and devices outside the GPE and Nexus (tested on a Nexus 7 2013). It’s good to finally have the official Google Now launcher on my Nexus 7 2013.
Will post about it if Google decides to bring it to other devices as well.
Introducing Google Now Launcher, available today for Nexus and Google Play Edition devices https://t.co/pVpqfVOrHm
