When is the next Explorer Anthology coming?

They haven't said specifically, but based on past announcements we know that:

• Khans of Tarkir is coming to Arena late 2023
• Pioneer Masters is coming 2024 and they expect to have Explorer at parity with tournament Pioneer by end of 2024

In that case, I would expect them to not release another Anthology until next year, and depending on when Pioneer Masters arrives maybe they won't even need to release another one

I don't think we've gotten an announcement about it yet, but for reference, this is the release history for the Anthologies, the date is when they LEFT the store:

1. Explorer Anthology 1 -- ended July 28, 2022
2. Explorer Anthology 2 -- ended December 13, 2022
3. Explorer Anthology 3 -- ended October 10, 2023

We had a LOONNGGG wait between 2 and 3, but I think the target is every 6 months. They should be every 3 months imo, I think we will see the next perhaps early next year, hopefully in February.
