"...will provide you with new events and new content from a completely different point in time. A new Registry family, 1920s Wizarding World, will provide three new Registry pages: Newt’s Menagerie, Circus Arcanus, and Paris Street. Each Registry page will provide four brand new stickers, allowing you to meet new characters and magical, fantastic beasts.
These events will feature unique Portmanteaus that provide a window into the past through AR experiences. Want to explore secrets hidden from the Muggle world? Hop into Newt’s Suitcase and see what quirky beasts lie inside. Intrigued about the magical government of the United States? Take a look around the MACUSA lobby. Feeling curious and want to see the most unique performances? Visit the Circus Arcanus and witness the fabled magical circus. Once you have collected five Wrackspurts from these Portkeys, you will be rewarded with a 1920s Encounter.
These unique Portmanteaus will only be available during 1920s Wizarding World Convergence events. To unlock a 1920s Portkey Portmanteau, insert a Key before the timer runs out. Any 1920s Portkey Portmanteau without a Key in it will disappear shortly after the 1920s Wizarding World Convergence ends. Once opened, you'll be rewarded with an exclusive 1920s Wizarding World Encounter and other valuable rewards!
Are you ready to see the wizarding world from a century ago? Our first 1920s Wizarding World Convergence is 7 August 12:01 a.m. - 8 August 11:59 p.m. local time."
Sounds like they're upping the Fantastic Beasts content, so who knows, maybe there's some progress on that front?
They're definitely changing the way the Portkeys work, which is a shame. This means a couple of things: 1) you'll have to have lots of slots open to pick them up in the first place or cover lots of kilometres during the event and 2) you'll have to use Silver Keys to get the most out of any Portkeys in your vault, because you won't be able to successively unlock them using your free Gold Key in the days to come. Not pleased. I think this is the first time we've had things removed from our vaults by their hand, too. Up till now, anything you had collected was yours until you decided otherwise. On the other hand, it does make it more likely they'll have plenty of them lying around so they can milk the rubes. I know the last few times they had special Portkeys, I'd used Silver Keys to be able to pick up more, and was left with unfilled slots in my vault and a feeling I'd wasted those keys. Hopefully that, at least, will change if it can potentially earn them even more money.
