While we still do not have a concrete "Yes" or "No" answer to that, there has been a recent development on that front.
The Weibo image does not reveal much about the OnePlus 7T Pro, except the display. The photos were leaked by a popular Weibo leakster Max J. The images made it to popular leaks aggregator Slashleaks a few hours later.
Global markets rocked by escalating trade fights
Soon after his announcement to impose additional tariff on the import of Chinese products , the stock markets in NY took a plunge. The 10% tariff will end up impacting a large number of consumer goods and electronic appliances which are imported from China .
The OnePlus 7 may not carry the same flamboyant design as the Pro in the series but it comes with primarily the same hardware - except for the absence of the third rear camera and the pop-up selfie shooter - and similar software experience with OxygenOS. This phone is placed in a case in these two images, so we don't really get to see the whole design. The phone appeared in two pictures, and do take this leak with a grain of salt, as the phone that leaked resembles the OnePlus 7 Pro quite a bit, and could be fake.
This year was a little different in that it saw a Pro model announced alongside the standard OnePlus 7, but based on the latest leaks, a OnePlus 7T Pro model could still be coming. Although the previous Developer Preview 3 landed for the OnePlus 7, 7 Pro, 6, and 6T all at once, for now only the 7 Pro appears to have Developer Preview 4 early. The Chinese smartphone manufacturer is expected to launch the OnePlus 7T Pro during the second half of 2019.
It's worth taking this leak with a pinch of salt as we're nearly three months away from the expected official launch of the phones.
