PAX planned several live events over the course of 2021 but one of them will be cancelled, at the least. The rest still have a chance of happening.
Coronavirus caused all the mass gatherings to be cancelled and that included numerous gaming-related conventions in 2020. The issue persists in 2021 as PAX East, which was meant to be held in July 2021, has been officially cancelled.
Still, the organisers are "cautiously optimistic" about PAX West and PAX Unplugged, both of which are on track to proceed as planned with in-person festivities. The first of these two events will last from September 3 to 6 while PAX Unplugged is on track for December 10 to 12.
Instead of PAX East, we will get PAX Online which will happen from July 15 to 18. Before that, there will be an Indie Showcase that will happen at some point but the organisers didn't specify when exactly.
They also avoided a lot of headache since no tickets were sold to potential visitors nor space to exhibitors at PAX East so there will be no need for any refunds.
As for the matter of the upcoming live events, the team will "continue to monitor the situation surrounding COVID-19, observe government guidelines and local laws, and defer to health officials and experts on what is deemed safe".
In short, it's still possible that PAX West and PAX Unplugged will get cancelled, all depending on how well the battle against the pandemic turns out.
