Kormiltsev is the Country Manager for HTC in Russia and The Commonwealth of Independent States (CIS). His tweet was short, but to the point, saying simply, "HTC One upgrade to 4.2.2 is planned for mid-June. By FOTA." (translated) So, it sounds like HTC One owners should be seeing the 4.2.2 upgrade, and Sense 5.0 tweaks before the HTC One Google Edition is released.
Of course, there have also been rumors about HTC offering a way for current One owners to install the Google Edition ROM, but we haven't heard anything new on that front. Also, this isn't the first time we've heard that the HTC One update to 4.2.2 is on the way in a matter of weeks, but this time the source is far more reliable.
