HTC hasn't completely forgotten its older devices as it continues talking up the HTC One. The One X+ is finally getting an update to Android 4.2.2, which is actually newer software than the current generation One in the US runs... but that's beside the point. The OTA is hitting Taiwan first, but we've already got a full system dump and a ROM based on it.
The software features are essentially the same as you'd see on other HTC devices running 4.2.2. Be aware this OTA is only compatible with the One X+ with SID HTC__621 (read: not the AT&T version). Here's HTC's official changelog:

InsertCoin ROM
The system dump is available for download on this XDA thread, if you are so inclined. If that's a bit much, there's also a ROM already based on this OS update. InsertCoin 5.0-1 is available for testing, but it's only compatible with the international HTC One X+ (sorry AT&T customers).
