CD Projekt Red has uploaded its own unboxing of said collector's edition, and we've embedded that below. It comes with a big old box, a figurine, a map of Night City, the game's setting, a cool looking artbook, a car keychain, a game compendium, a steelbook case for the disc itself, a survival guide, a whole bunch of stickers, and, of course, a copy Cyberpunk 2077. Again, pretty meaty.
It's worth noting that the standard edition also comes with the map, stickers, and a few other little things.
