They are going to postpone the Game Developers Conference this March.
in a quote on their page:
"Having spent the past year preparing for the show with our advisory boards, speakers, exhibitors, and event partners, we're genuinely upset and disappointed not to be able to host you at this time .
We want to thank all our customers and partners for their support, open discussions and encouragement. As everyone has been reminding us, great things happen when the community comes together and connects at GDC. For this reason, we fully intend to host a GDC event later in the summer. We will be working with our partners to finalize the details and will share more information about our plans in the coming weeks."
Hopefully this can be recheduled with all developers jumping back in later in the year.
