Normally, would the price of iPhone 5s get cheaper if iPhone 6 gets released?

Hi! I know the iPhone 6 and 6 Plus were already released in some countries worldwide, but here in the Philippines, both phones will be released by mid-November. Does that mean that by the time iPhone 6 and 6 Plus becomes available in our country, normally would the prices of iPhone 5s and 5c become a lot cheaper? I'm planning to buy an iPhone 5s but I'm waiting for its price to become cheaper.

It did, walmart had 5S for $79 on 2year contract

It normally does…
When the company's flagship phone changes the previous one gets a lower price

Yes I think that's how it works

Yes it does & has.
