Ethereum Fork: Metropolis (September Price INCREASE???)

Ethereum is entering it's pre-final stage of the Roadmap, Metropolis next month. With the developers announcing better security/anonymity, faster speeds and overall an improved experience with Ethereum, I think the price will rise long term. There's only a few things though.. before Serenity, Metropolis actually needs to fulfill its needs. Ethereum's team NEEDS to keep its promises or else speculation could force the price to go sharply down. What do you think will happen with Ethereum? Where do you think it'll go pre-Metropolis?
