This is a user-to-user technical support forum. No one here would know anything about Apple's plans for pricing in the future. Speculation is prohibited by the terms of use of these forums.
In the past, Apple kept an earlier version of the phone available at a lower price, sometimes also with a smaller memory configuration when they release a new phone. They have not, as I recall always done this, though it has been the norm recently. Whether they will continue to do so is something we will all have to wait until the next iPhone is announced. And, although Apple has announced new phones the last couple of Septembers, we have no official announcement that they will do so this year.
