Here is official(!) unboxing video
I've actually found unboxing videos to be useful when returning stuff to B&H Photo since they require that you return all parts of the item including packaging. They remind you what exactly is in the boxes.
@Tommyboy - I just returned my GH5 to B&H as well. Credit processed 2 days after they received it. Hopefully yours is anyday now. GH5 deals through this site is another matter. I paid for one through the deals page here on March 30th and still waiting for the camera. Maybe I should've stuck with the B&H one.
