Prices to expect for 3GS/4/4S after iPhone launch

[rak007]

Sorry if the thread seems repetitive.
I have to buy iPhone 4S for myself and another iPhone (either 3GS or 4) for my dad (he has never used smartphones or iPhones). I am going to buy these 2 phones after tomorrow's announcement in hope of seeing reduced prices in used market (with craiglist being cheaper i guess).
What prices am i expecting to see for.. (used)

iPhone 3GS 8GB
iPhone 4 (8 or 16GB)
iPhone 4S (16GB or 32GB).

after tomorrow's new iPhone announcement.

I am looking for no-commitment phones so i won't be going to carriers to buy.

Craigslist and eBay prices may drop.

AT&T/Verizon may have sales on 4/3GS. Usually after, Apple makes an 8GB version of the previous model and sells it for $99.

Most likely:

3GS: Gone
4: $0 with 2yr contract (8GB)
4s: $99 with 2yr contract (8GB)

iPhone 4S prices have still not gone much down as i expected it would after the launch. I know the new one launched just this morning but i hoped for lower priced 4S.
New unlocked is 549$ for 16GB + tax.

If you're willing to buy used, you'll see a considerable drop in the price in the next few days as people sell their old units to get the 5.

Yes i want to buy Used only but still i see most listings ending upward of 375$ for 16GB model. I am not sure if i am asking too much but i am expecting to get a 16GB for under 350$ and 32GB for under 400$.
Not sure if i will get it.
Craigslist listings in my area are crazy. Someone is listing his 32GB used 4S for 700$. Insane and stupid pricing.
