GPC released a new Mavic 2 hard case (GPC-DJI-MAV2-SC) that’s able to hold the Smart Controller.
If you already own one of GPC’s other Mavic 2 cases, they are selling a foam replacement (GPC-DJI-MAV2-SC-F) so you can upgrade the foam in your existing case.
Here's a video from FlyPath that takes a closer look at this new case:
