There is a European Tour and a new PDGA Europe organization. Wouldn't surprise me if the DGWT team shifted focus to more support for and growing the Euro Tour events to rival the NT events in America.
This is the most likely scenario and a smart decision.
The whole thing just proves (again) that the U.S. Professional Tour will never have big time sponsors throwing millions of dollars into the sport, or prime time coverage (beyond Sportscenter).
That's not to say that there can't be a successful bottom-up-model Pro Tour that helps grow the sport/tour; through more industry sponsorship, support and involvement. Not just by pouring money into tournaments, but also supporting disc golf media sources and influencers.
When you find success in that situation you're more likely to see sustainable third party/outside support, than if some big shots threw money around for year or two and then pulled the plug.
But kudos to them for trying.
