"Gurman says Apple engineers initially hoped for a June launch, presumably at WWDC 2018, but noted the AirPower has been delayed due to technical challenges, including the potential for overheating, complex multi-device charging circuitry, and software bugs with the accessory's on-board firmware."

Apple either gets there in the end, or gives up. I reckon they'll give up... Its already in the 'too hard basket' now. Just like the TouchID under the screen of future iPhones
