Android 7.0 won't offically come to Snapdragon 800/801 devices?

it looks like some popular devices will miss the party. For example, Sony's announcement didn't include the Xperia Z3, HTC's announcement didn't include the One M8, and Google isn't planning to release Nougat for the Nexus 5. These three devices have two things in common. First, their age: they were all released in 2013/2014, making them at least two years old. Secondly, they all use the Snapdragon 800 or Snapdragon 801 processor.

Speculation about support for Android 7.0 on the Snapdragon 800/801 was further fueled by a tweet from LlabTooFeR, the developer behind the MaximusHD ROM, “Qualcomm will not release graphics drivers for 800/801 CPUs. So HTC One M8 and other devices based on this CPU won't get official Android 7.0.”

Qualcomm  statement:

“Qualcomm Technologies, Inc. works closely with our OEM customers to implement and support varying versions of the Android OS across our Snapdragon chipsets. The length of time a chipset is supported and the upgradable OS versions available to consumers are subject to the OEM product lifecycle. We recommend you contact your device manufacturer or carrier for information on support for Android 7.0 Nougat.”
