It's been unofficially announced that the WSOP will be at Bally's & Paris in 2022, and will take place over the summer again

Even though the WSOP is just concluding now, it appears we will be playing again in just 7.5 months.
Bally's and Paris will host the events in their convention space. The two hotels are physically linked together, and you can go between them without walking outside.
I do suspect parking might be a complete fiasco, as the structure doesn't seem big enough to hold all the WSOP players plus the hotel guests. However, John Mehaffey says that the big parking lot right behind Bally's can also be used:

There are also rumors that Bally's will change to be called "Horseshoe Las Vegas". This would be to prevent confusion with the newly-named Bally's casinos which are quickly being rebranded by the Bally Corporation which owns them. Caesars still has the right to use Bally's for that one property, but they'll probably get away from it, so as to both end any confusion and to avoid advertising the competition in other markets. They own the Horseshoe name, which came along with the 2004 Binion's purchase, which also got them the WSOP. There is presently no Horseshoe is Vegas, but Caesars has them in other markets.
This should make the hotel situation a bit better for the WSOP, as there will be a lot of places to stay which are walking distance from the WSOP, even for those who don't wish to stay at Bally's or Paris.
