It looks like Build 2018 is headed back to Seattle this year. Microsoft watcher WalkingCat, who has a solid track record when it comes to leaks, took to Twitter with what looks to be an official graphic with the dates for Build 2018. According to the graphic, the conference will return to Seattle and run from May 7-9.https://twitter.com/h0x0d/status/960901377768620032
Based off of last year's conference, the timing and location aren't surprising. Build moved to Seattle in 2017, taking place around the same time in May. In previous years, the event had taken place in San Francisco in April. What makes the reported timing more interesting is that it would put Microsoft head-to-head with Google's I/O conference, which will run from May 8-10.
Build 2017 gave us an early look at what features would eventually make it (or not, in some cases) to the Fall Creators Update. We'd expect Build 2018 to offer a similar look at what's coming later this year in the forthcoming Redstone 5 update. It should be interesting to see what's coming down the pike as Windows 10 continues to evolve, and Windows Central will be there to cover the event.
