Don't Wait For Wireless Charging
Don't wait for the OnePlus 7T if you're waiting for the company to finally offer wireless charging. Or a headphone jack for that matter. With the 7 Pro they finally killed the 3.5mm headphone jack and it's not coming back.
Furthermore, OnePlus reaffirmed their position that they'll never offer wireless charging if it's not very fast. And while we're sure they're working on a super-fast type of wireless charging the technology isn't there yet.
When your OnePlus 7 Pro can go from 0-70% in around 25 minutes with a cable and Dash charger, but takes over an hour using wireless charging, that's not a seamless experience they want to offer.
The OnePlus 7T could finally be the device (and now is the time, IMO) that they offer wireless charging, but don't bank on it.
