Motorola is continuing its tradition of being transparent about which devices are on the docket for OTAs. The company's online tool has been updated to indicate several new devices will be joining the Android 4.4 fold.
According to Motorola's site, the Droid RAZR HD (regular and developer edition), Droid RAZR MAXX HD, Droid RAZR M (regular and developer edition), Electrify M, and the Atrix HD. So, there are some surprises in there, especially the Atrix HD on AT&T. That device never really caught on, and the developer edition isn't listed as getting the 4.4 update – only the AT&T version. We can't rule out that this is a mistake.
The tool only says the updates are coming, not when. Some will obviously arrive sooner than others, mainly the devices added in the last update. At any rate, there are sure to be some happy Motorola customers today.
