I predict Ethereum will be between $380 and $400 before the end of 2017.

Depending if they decide to get the coin forked or not the price can vary from that or lower so it's better for them to not get it forked this year so the price will go up.
What? I surely hope the eth team doesn't think like that, it should be about the tech and the coin, not about trying to reach some artificially inflated price.
