HTC One nexus to get Android 4.3 in July

The main advantage of Nexus Edition of the HTC One is to get updates sent out directly from Google. 

The HTC One Nexus Edition will be launched with Android 4.2.2 installed. But as per  HTC ROM developer LlabTooFeR, Google will be updating the phone to Android 4.3 a "few weeks" after release. Most likely, the Nexus Edition of the Samsung Galaxy S4 will also see the update quickly. As Google has agreed to delay the release of Key Lime Pie at the request of Android handset manufacturers who want to update current models to Android 4.2.2 before Android 5.0 is released. Based on some recent speculation, we could see Android 5.0 launched on the HTC T6, the phablet sized version of the HTC One.
