HTC’s product management chief, Mo Versi has confirmed on Twitter that several North American carrier-locked variants of the HTC One M9 and One M8 will be getting Android Marshmallow over the coming weeks.

Beginning this coming Monday, January 18th, the Marshmallow OS update will be pushed to Sasktel, Rogers, Wind and Videotron HTC One M9 owners in Canada.

As you’d expect, following that tweet, many HTC One owners with different carrier-locked versions were keen to known an ETA for their Marshmallow update. In response to those, Mo Versi stated that the HTC One M8 on Sprint will get the new software from the middle of next week, while the T-Mobile variant is on schedule for a January 25 release.

Sadly there’s no specific news for AT&T or Verizon users, except to say that HTC needs a “few more weeks” before the update is ready for the HTC One M9 on AT&T.
