This is not entirely correct. Until now, all countries outside the Schengen area were blocked from travel into the EU (visa holders like @loose_unit excluded). The US "only" did not make it on the list of countries who are now allowed back in.Well, as of today, the US is off the list of countries who can travel to the EU. Maybe see what happens in a month I guess.
I am hopeful that next year intercontinental attendance will be back on track.
