We'll see if it actually happens in person. The Guild is definitely watching the numbers too. They have been doing planning all along to shift to a virtual version if needed; that's been happening parallel to the usual planning. If it switches to all virtual, it will be spread out over a few weeks, rather than trying to compress it all into a few days.
If I didn't already have a registration because I'm speaking, I'd do a virtual pass. That's a much more affordable way to attend than would normally be possible anyway. However, if you have a team of people, a regular registration that would convert and allow you to share with coworkers would be a good choice.
