This is unofficial, but the Seattle Times has a map showing the rumored closings. seattletimes.nwsource.com/flatpages/businesstechnology/

It shows the Sheridan Road location as closing as well as the Altus location. These make sense, as Starbucks has said closures would be of stores opened 2006 and after. If it's not true, Starbucks is getting what they deserve. By saying 600 stores are closing, but not saying which 600, they are leaving everyone to guess, so such conjecture is very predictable. It is as though they wanted people to think their store was closing.
UPDATE
It's official, Altus is closing as is Sheridan Road.
