The HTC One successor, whatever it might be called, will be the first handset running HTC Sense 6, the next phase of the UI that will run on top of Android.
The info comes from our old faithful bean-spiller evleaks, who wrote on Twitter with his typical brevity: "HTC M8 will be the first Sense 6.0 handset."
As revelations go, this isn't high up on the mind-blow-ometer, but the fact we're hearing talk about the HTC M8 right now suggests the phone is well on its way - set for a MWC 2014 reveal perhaps? All eyes on February, then.
Word of the next HTC flagship began swirling back in July, while the most recent version of Sense is 5, which lets users finally turn off BlinkFeed.
Guess you could say it… makes Sense to us
As a name, HTC M8 will be just a codename in the same way the M7 was for the One. A lot of people are referring to the phone as the HTC One Two at the moment although that one also seems unnecessarily complicated.
Perhaps HTC will go simply with the HTC Two, or give it an entirely new, non-number-based name. Place your bets now.
As for what Sense 6 might actually look, that one remains a total mystery, but there's every chance we could be in line for a total overhaul.
