Owners of last year's Moto G phones have not been forgotten – Lollipop inbound "soon"
It comes in the form of an update for the Motorola Update Services app. In its changelog, one can see that the app needs to be updated in order to be ready for a future Moto G Lollipop upgrade. How far into the future that would be – we can't really tell.
Hardware-wise, the old Moto G is still pretty much on-par with this year's iteration of the model. They both sport a Snapbragon 400 SoC with 1 GB of RAM – the 2014 edition Moto G has a slightly larger screen (5" on the new model, 4.5" on the old), higher resolution camera (8 MP on the new, 5 MP on the old), and a slight bump in internal storage (16 GB vs 8 GB). With such a negligible upgrade, the original Moto G is obviously still quite relevant, and making the decision to keep it is a natural decision. It's good to see that Motorola acknowledges that and will keep its users up-to-date.
