How much will this fall's iPhone cost?

Normally, when a new iPhone comes out, it replaces the old one's advertised prices of $199, $299, etc.

For example, if you don't know what I'm talking about, the iPhone 4 cost $199 (advertised price) and when the iPhone 5 came out, it replaced that cost of $199 and the 4 became $99. Do you follow me?

I'm wondering if the iPhone this fall will follow that pattern, or be more expensive than the 6.

I'm in need of a new phone and I can't decide if I should buy the 6 now or wait and get the newer one this fall for the same price.

Hopefully someone with a background in phone sales will be able to answer this! But all opinions are welcome and appreciated!

It would maintain that pattern as it has since 2008, however by that time AT&T (as they already have) & Verizon would have switched from the 2 year contracts that gave those $199, 299 prices to the Next & Edge programs respectively. So at least Sprint (unless they too follow them) would have the same $199, 299, 399 prices.

Anyone answering is just guessing.

It could be 50$ more i guess.
