Not sure if this got posted elsewhere.
Very interesting to me for two reasons.
First IAD is on the list in 2018. Amen.
Second, curious about London. They have the best lounge already, no?

Australian Business Traveller - United Airlines lays out Polaris business class lounge roadmap
Newark and San Francisco will see Polaris lounges open in mid-2017, United Airlines tells Australian Business Traveller, although both will be 'phase one' developments with a 'phase two' slated for 2018.
Polaris lounges at Los Angeles, London's Heathrow Airport and Houston's George Bush Intercontinental Airport are all slated for late 2017, United tells Australian Business Traveller.
2018 will also extend the Polaris network to Hong Kong, Tokyo Narita and Washington's Dulles International Airport, although United Airlines was unable to provide a more detailed timeline for those lounges.
