Google Play Editions of the HTC One and the Samsung Galaxy S4 are getting their Android 4.3 update through an OTA update. Its just been a week since the Nexus devices officially started receiving their Android 4.3 Jelly Bean updates, so for future reference the Google Play editions will possibly get updates as soon as Nexus devices.
Although Android 4.3 is just an incremental update, but it does bring OpenGL ES 3.0 support for console-like gaming, Bluetooth Low Energy profile support, restricted user profiles and some performance improvements to boot. Check for the update notification, and tell us if you find some improvements with your Play Edition phone.
