Now that the official source code for Nougat has been released by Google it won't be long until we start to see builds of Nougat for all devices. Cyanogen has already started to merge source code from Android 7.0 under the CyanogenMod 14 umbrella for the Nexus 5X. It won't be long before we start seeing work on other devices as well from the CM team. CM devs are volunteer developers so don't go asking for ETAs. Now that the source code is dropped we will start to see the release of Nougat roms from other developers as well. The first devices to receive roms will likely be the devices that Google has already provided updates for. These are exciting times in the Android community for sure!
