2020's Game Developers Conference (GDC), originally set to be live from March 16th through March 20th, was one of the first tech shows to be cancelled in wake of the Sars-Cov-2 outbreak. Now, the organization has announced that the event has been rescheduled a full 5 months later for August 2020. The event has been set for a three-day "GDC Summer" still taking place in Moscone Center in San Francisco, USA, starting August 4th and ending August 6th. Passes for the exhibition are already available, with early takers being offered heavy discounts over the on-floor passes.

GDC has been the stage for a number of high-profile gaming and services announcements, with the 2019 edition seeing announcements for Google's Stadia, EPIC Games detailing new features for its Unreal engine, and AMD taking the lid of their (then) upcoming 3rd generation Ryzen CPUs. Intel was first expected to detail their Xe graphics architecture at GDC 2020. It remains to be seen whether the blue giant will still be doing so in wake of this delay, or if the company will find an in-house (albeit likely online) alternative to get word of mouth flowing on their upcoming high performance graphics architecture.
 
I'm glad to see the event was not cancelled altogether.

I do wonder if it's a good idea to pick a new date yet, if it's not clear how long it'll take before the virus runs it's course. Granted they can always postpone/cancel it later on.

I think that is kind of the plan since if it goes into June they can always cancel with enough time to not feel rushed. If they need to push it back again I don't see a point since you get into being near 2021 event.

My crystal ball says that's about the time the zombie apocalypse will occur.
