if a price cut is going to be the next big thing from OP, i'll be disappointed. I'd still bet on the one plus two being announced.
All other brands have already made price cut to their flagship (Meizu, Xiaomi...). I have bought my Iuni U3 at 1599 yuans and it will drop down to 1399 yuans next week. So I would not be surprised Oneplus do the same.
