Personally, I don't see any price cuts happening on it. People only see the $199 and $299 price tag for the phone, but not the price tag for a 2 year contract. Once more and more people realize how much money it is to own an iPhone, I think they'd be willing to settle for the current price of an iPod Touch and a cell phone. However, I can see the 8Gb model getting dropped for the line up.
If they introduce a 64GB version, weather it's September 9th (or 22nd) or in February, they're gonna have to lower the price by at least $100.
Especially since nobody's gonna pay $600 for a 64GB iPod, even if it has internet.
