2015's Moto G will be water resistant
It apparently has an IPX7 certification, which means that the Moto G will be able to withstand being submerged in up to one metre of water for up to thirty minutes.
The Moto G will also be 4G-enabled, which is reassuring considering past Moto G's haven't always been. Other specs include a quad-core processor, which previous rumours suggest will be the Snapdragon 410, a 13 megapixel camera, a 5 megapixel front-facing camera, and a 2470 mAh battery.
