"All of these devices are about to receive a new software build, yet the Android version will stay at 5.1.1 even after you apply the update. The new build number is LMY48M, and this should be identical for all of the aforementioned products except carrier versions of the Nexus 6. In this case there will be different build numbers - for example T-Mobile's is LYZ28K,"  GSM Arena reported.

Adrian Ludwig, lead engineer for Android security, have somehow informed the general public about the Nexus updates that will be happening soon so that these devices will have the latest updates  for their devices.  "Nexus devices will receive regular OTA updates each month," Android Official Blog announced.

Android security Engineer also reiterated that the updates will mostly carry security patches, but will have the usual platform enhancements.

Google updates for the Nexus models are moderately sized files, 30MB for the T-Mobile Nexus 6 and 20MB for the other Nexus models, and will not really take that long. This small chunk contains minor security patches and fixes for minor bug issues.  Feature wise, very minimal at the moment, but there will be updates happening on a monthly basis.

Android users had a scare a few months back when the "Stagefright" vulnerability emerged.  The exploit was quickly immobilized via security patches.
