Any devs still holding out hope of an invite to Steam Dev Days this year should probably pack it in, as Valve's Tom Giardino noted on Twitter this weekend that there won't be one in 2017 -- and 2018 isn't looking good, either.
It's something devs should know about, but not at all unusual; after launching Dev Days in 2014, Valve took a pass on 2015 because, according to a company representative, it didn't make sense in a year when Valve didn't debut a bunch of new tech.
In 2016, the year the HTC Vive and other VR headsets made their commercial debut, Valve decided to revive its Steam developer conference with a special focus on VR.
While there won't be a similar event this year, curious devs can of course still go back and watch Dev Days talks from 2014 and 2016, which feature speakers like Michael Abrash (when he was still at Valve), Tim Sweeney, and a number of other notable game industry types.
