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.
It is not like that, I believe, a coin value doesn't depend on how good the dev, support and marketing although they're working hard to keep and maintain their coin stable but there are so many aspects that needs to be considered. A large scale of miners were shifting from Bitcoin into Bitcoin Cash so then there's a sudden price motion and it cased a gap of Bitcoin's price drop and Bitcoin Cash' pump.
Ehtereum on the other hand doesn't rely on these situation, if only there's number of investors that will going to support Ethereum and has a large miners also that helps transaction faster then it'll affect also the price hike. traders and miners has the biggest role for cryptocurrency value and marketcap.
