I posted this as to what I seen: Via Droid Life..
It looks Like Lollipop is coming to the M7 the model phone before the M8 but on Sprint I have not seen anything yet of it coming to Verizon but that could change and if it does.! might not hurt To Not jump into it real Quick and update.! the update as I mentioned when it does show up.! it is best to watch N see if there's any issue in it.. If it's reported there are minimal to no issue's go ahead & proceed if you feel the need to.. That is the way I approach these updates if I feel it'll benefit my phone I update but if I see problems others are witnessing I hold off, because once you get the update there is no turning back once the issues start..
