Last week, when Motorola sent out a save-the-date to the press, there was no hints on what device will be unveiled. That changes now, as the company has begun sending out the actual invites, which clearly indicate that a shatterproof phone will be the star of the event.

There have also been rumors that the Moto X4 will also be unveiled on the same day, but the invite sent by Motorola has no hints of that so we’ll likely have to wait a little longer for that one.
