HTC America's president Jason Mackenzie responded to some questions on Twitter concerning the HTC One upcoming Android 4.3 update.
He says the Android 4.3 development for the HTC One is right on schedule and the rollout will start by the end of this month as promised. This applies for both the US and the EU HTC One units.
Update: To lend further credibility to this info, the following image was sent to us by one of our readers. It shows the HTC One (a blue one!) running Android 4.3. Allegedly, the image was shot at IFA. Thanks for the tip, Daki!

It seems HTC will manage to seed the Android 4.3 update ahead of the competition. Samsung is supposed to bring that release to its 1H flagship in October, and Sony is yet to announce a schedule for the Xperia Z updates.
