Here's what they've announced so far:
The WSOP will take place from May 26-July 15.
The Big 50 is returning this year, after getting over 28,000 entries in its inaugural year of 2018. (I finished 666th there, easily cashing for about $3k). The event will have a $500 buyin once again, with 50,000 starting chips and 50-minute levels. Starting flights will be from May 28-May 31. The reentry status is unclear, but presumably there will be at least one reentry per flight. It is also unclear if the first buyin will be rake free again, or if that has been changed.
The Main Event's starting days will be July 1-3. July 4 will be Day 2 for flights A and B, and July 5 will be Day 2 for flight C. July 6 will be Day 3, and it will continue playing every day forward from there, expected to end on July 14. Late registration will be allowed through 6 levels, but that's actually 12 hours into play, because each level is 2 hours. This will allow people to register not just on Day 2, but also during the entire first two hours of Day 2. The buyin will remain $10,000, as it has always been. If you recall, I finished 128th last year, for about $59k, out of 8569 entrants.
The Seniors event, which is for ages 50 and over, will begin on June 18, and will again be a $1,000 buyin.
It will again take place at the Rio, but could move to the new convention center near The LINQ in 2021.
May 26 is the earliest start to the WSOP in more than a decade.
It has not yet been announced when the full schedule will drop.
