From Sunday 28 April 2019 there will be some changes to train and bus services to allow for the integration of Sydney Metro into the wider transport network as well as to match service levels to customer demand.
Key adjustments being made include additional services along the T1 North Shore Line, and renaming the T1 Northern Line to the T9 Northern Line. Some bus routes in the Upper North Shore area will be adjusted to better connect with train services, additional services will be added in other areas and some bus routes across Sydney will be renumbered.
Services are changing ahead of the integration of Sydney Metro into the network in May – Transport NSW Blog Collection.

Transport for NSW is yet to report the planned opening date for Sydney Metro Northwest, however it is rumoured to be May 5. This is contingent on the approval of the National Rail Safety Regulator approval for operation.
More changes for North West bus services are expected to occur in July and later this year as part of staged changes to the transport network to avoid any disruption and provide a seamless transition to a new network.
Yes, some of the Metrobus routes were rebranded as part of the changes for the new Metro. It is believed, but not officially confirmed that this had something to do with avoiding confusion

I hadn’t heard they were rebranding the Metrolink buses. Is this to avoid confusion with the forthcoming (rail based) Metro service?
