Trainers, I don’t like to be the bearer to bad news, but it looks like we are not going to see a new EX Raid Boss anytime soon.
As we all know, Mewtwo will start to spawn as Raid Boss from September 20 at 1:00 PM PDT until October 23 at 1:00 PM PDT, meaning it will be available for everyone for a limited time (I really hope to see its shiny form too).
A lot of Trainers were hoping to see a new EX Raid Boss after October 23, but as now ‘confirmed’ by Niantic support, we might not see a new EX Boss anytime soon.
Here is the email:
Please have in mind that Niantic Support was proven to be wrong many times in the past, so take this with a grain of salt. After all, it seems like they barely know anything about the game mechanics. People should ask them only for technical problems and not for future updates and events.
