LG says that the major carriers in the States will offer these add-ons or you can purchase them directly from the company. The Cam Plus module that adds a grip, camera controls and takes advantage of the G5's modular design is the most affordable of the group at $70. If you're looking to nab the VR headset, Tone wireless audio headset or 360 Cam, be prepared to hand over $200 for each of those. Unfortunately, there's no mention of the BB-8-like Rolling Ball, but LG did note that more third-party companion devices were on the way.
