It's unclear exactly when the Lumia 929 is going to hit Verizon, but what we do know is that the device is going to be a "GDR3" update to the current Nokia Lumia 928. By that, we mean that the hardware is getting bumped up to the levels supported by the Windows Phone GDR3 update: a Snapdragon 800 processor and a 5-inch 1080p display. The device is also expected to carry a 20MP camera similar to that on the Lumia 1520, and 2GB of RAM.
We're sure that Nokia wants the device on shelves before Christmas, but we'll have to wait and see. There have been multiple release dates rumored and passed by without seeing the device, so there's really no telling when it will be released.
