happy to help.
it is really hard to say what will be the price because there are a lot of roadblocks ahead.
here are just 2 of them:

1. some governments are gonna regularize the ico for startup companies, that means those companies will have to pay taxes on the total amount of ether not only for the ether that they are changing back to FIAT.
2. will ether move or add the option of mining by POS . if so a lot of miners will hold close to their ether in order to mine it and they wont trade it.

if i see it right, ether will surely reach 3500 usd by the end of 2018.
