No clear indication of what the software update will bring
We've already seen Motorola roll out a rather quick Android 4.4 update for the Moto X, and now Droid 4 owners are receiving a soak test invitation. Shortly after rolling out the soak tests on the Moto X, Droid Ultra and various other devices the update starting hitting officially, and we hope for the same here. While this update is likely to keep the phone on a lower version of Android — Motorola's support page still claims the Droid 4 won't go past Android 4.1.2 — we'll never turn down an official software update on an older device.
Invites are going out now, so we can expect to wait a few more days for software to start hitting devices. Hopefully if all goes smooth they will be able to roll the update to everyone rather quickly. Keep your eyes on your update screen and be sure to let us know if you start receiving the update!
