Those are the global offerings for people who can't attend Go Fest :)
Edited to add, from the Pokemon Go blog: "Trainers without a ticket to the event won’t be able to see any Pokémon or PokéStops in Lincoln Park, but Trapinch, Feebas, and other Pokémon featured in the habitats of Pokémon GO Fest will appear more frequently all over the world during that weekend. The Cheering Pokémon, Plusle and Minun, will also appear more frequently worldwide as Trainers complete themed Field Research tasks. Catching Plusle and Minun will result in bonus Stardust, and lucky Trainers might even discover their Shiny versions! The Alolan forms of Diglett and Geodude will be in on the fun, too. Beginning that weekend Alolan Diglett and Alolan Geodude will be appearing globally for the first time in Pokémon GO. Don’t miss the chance to encounter the unique forms of these Pokémon."
