The main floor of AX is devoted to merch. Mainly, you're buying a ticket to buy cool imported stuff or something from your favorite online artist. And you still possibly can.
If AX was really happening you could take a trip downstairs and visit Artist Alley and who knows, maybe air conditioning would be at a reasonable level. But it's not happening and we're getting online panels. We're also getting only links to the artists of Artist Alley.
Here's the official link list from the Anime Expo site.
