Pete Lau, the chief executive officer (CEO) at OnePlus, has confirmed that a new phone with an imminent release will have a 90Hz screen. The use of the eptithet "affordable" also connected to this phone suggests that this device is the 7T rather than the 7T Pro. This, then, may not go down well with those who already own the 7 Pro.

Sure it sucks that oneplus might bean the customers who bought the more expensive thing first, but it could be worse. Apple and Samsung have been doing the beaming for years. At least with this you get something for cheaper, rather than less for more.
It's called progression folks. It's a good thing.
Why is it bad news for anybody? Nobody guarantees that something better won't ever come out after your purchase of anything!
Besides, OnePlus 7 buyers should have wised up when OnePlus increased the price so much, besides removing so many features like the 3.5mm jack. I've said at the time that buying it only encourages OnePlus to increase pricing henceforth. You deserve whatever you asked for!
