Of course, ethereum's technology is not perfect and they have already postponed new network upgrades many times, but even if these updates were installed it would not have had a significant effect on the market situation and the price of the eth. The market is too bad to even respond to the good news on the project.
Hope that the fork of Ethereum which is planned for the middle of January 2019 will bring many positive changes. Suppose, the price of the altcoin will grow a lot. Thus, ETH can gain much next year.
