Microsoft held Build in Seattle at the Washington State Convention Center last May after hosting the event in San Francisco for the previous several years. Before last year, Microsoft had held Build in Seattle once previously -- a rainy November 2012.
The current Build 2018 page does not specify exactly where in Seattle the show will be held.
Twitter user The Walking Cat (@h0x0d) posted on Feb. 6 a slide with the alleged new Build dates. I asked Microsoft officials to confirm -- but they would not. However, the updated Build 2018 page is live now. So, it's official that The Cat was right again. (Thanks to Rich Woods from Neowin for the tip-off.)
As customary, Microsoft isn't expected to share any information on the planned topics to be covered at this point. Build 2018 registration will open Feb. 15. Once registration opens, developers will be able to go to http://build.microsoft.com to register. The full conference pass is going for $2,495.
Microsoft will already have started rolling out Windows 10 Redstone 4 (slated to be available around April 2018 or so) by the time Build 2018 convenes. Maybe we'll hear some early info about Redstone 5, due to roll out around October 2018 at the event. I'd assume Progressive Web Apps support in Windows 10 will be a hot topic. And perhaps Build 2018 also will be where Microsoft goes public about what it's doing under the Windows covers with its Windows Core OS (a.k.a. AndromedaOS) and composable shell work.
Microsoft will likely be banging the AI drum at the event, as well, so talks on cognitive services and Cortana could figure prominently on the agenda.
