We’ll see, but reading it again the livestream they talk about definitely seems to be for the US Open as a whole, rather than specifically a new edition thing.
‘The event in Texas will be part of the US Open in Dallas, which is being held at the Esports Stadium Arlington, and runs from the 16th to the 19th of May. Attendees must also have a ticket to the US Open event, though there will be a live stream starting at 7pm local time on the 16th.’
