Nexus 4 wireless charging - sold as default?

Will the wireless charger ship with the device or will it be as an accessory that can be purchased separately? I can't find any wireless chargers on the Play store, but the phone itself is actually advertised as "Totally Wireless". Any help? I've seen a lot of people talk about it as if it's obviously an accessory... Have I messed something?
