Future US Opens/PGA Championships

Anyone know what some likely courses are for around 2024-2030? When do the respective organizations start making these decisions?

A player on the web.com tour told me that the USGA and PGA were at the Nationwide Invitational in the web.com playoffs looking at The Ohio State University Golf Course (Scarlet) as a possible destination for either a US Open or PGA Championship in 10 years.

Also some rumors out there that the Open will come to LACC in 2023.  That'll be fun. :)

I'm still an advocate for bringing a US Open or PGA to the Southwest.  Our part of the country has fine courses and is an afterthought when it comes to these events.  If it's too hot, toss us a bone, like a Ryder or Presidents Cup.

To update the future major venues, in order of US Open/Open Championship/PGA Championship....

2016: Oakmont, Royal Troon, Baltusrol
2017: Erin Hills, Royal Birkdale, Quail Hollow
2018: Shinnecock Hills, Carnoustie, Bellerive
2019: Pebble Beach, Royal Portrush, Bethpage Black
2020: Winged Foot, (presumably) St. Andrews, Harding Park
2021: Torrey Pines, TBA, Kiawah Island
2022: The Country Club at Brookline, TBA, Trump National
2023: L.A. Country Club, TBA, Oak Hill
2024: Pinehurst, TBA, TBA

I'd presume that the 2021-24 Opens will be, in some order, Lytham, Muirfield, Liverpool and St. George's.  It's also possible Troon goes back into the 'first half of the decade' rota and bumps one of the English courses to make it more of an even mix of English and Scottish (and now Irish) courses.

I also wonder if Trump National will actually end up hosting the 2022 PGA, or if it'll lose the tournament due to Trump's various offensive marks.
