From here: Here's what Motorola smartphones will be updated to Android 5.0 Lollipop
Motorola confirmed that it would bring Lollipop to the following smartphones: Moto X (1st and 2nd generation), Moto G (1st and 2nd generation, plus the Moto G LTE), Moto E, Motorola Droid Ultra, Motorola Droid Maxx, and Motorola Droid Mini. The exact timing of the updates depends on Motorola’s partners (i.e. carriers), but we should hear more on this soon. In any case, it’s nice to see that even the cheap, low-end Moto E will be updated.
