We'll see! There are so many problems with wireless charging that I don't see it becoming truly mainstream. Not being able to use your phone while charging is the most visible one (maybe 15W via magsafe will make it fast enough it doesn't matter). I also have trust issues with wireless charging in general - I got a free wireless charger from TripleByte once that overheated my phone and only got it to 60%. I'm still hoping for USB-C
