According to some news site of questionable reliability, Geek News Now, PAX South 2021 may still be a thing. But it'll be a February thing, at the earliest, and possibly a May or June thing. To wit:
Contrary to popular belief, it is not “Game Over” for PAX fans in San Antonio.
For months, rumors have swirled that the event would be outright canceled due to the pandemic. Even before that, the were rumblings that the convention would be moved to Dallas or Houston. Geek News Now was able to exclusively learn that the large gaming event, typically held in January along the famed River Walk, will be moved to February 19-21, but still at the Henry B. Gonzalez Convention Center.
There are still quite a few things up in the air, due to the impact the COVID pandemic has had on events of this scale. I spoke to a source at the Convention Center main office, who answered my questions. These answers were confirmed by another source at Visit San Antonio and additional information provided by a source in the Mayor’s Office in San Antonio.
