What affect will the new metro lines have on Cammeray property prices?

With the announcement that there are planned new lines for Crows Nest and North Sydney. How will this affect Cammeray? Will it see its property prices increase? I know completion is not expected till 2020 but will they also be a surge in new housing?

affect the values of properties in Cammeray, even though it's not due to complete until 2020???
