Is there a new Showdown for TA3?

I am stuck at work.
I was wondering if you guys can tell me if there is a new Showdown for TA3?
Also, tell me what the format is? Is it like TA2 Showdown, meaning one for each league?
Thanks

There’s East, West, Central showdowns

There are 3, one for each “region”. So there is an “East” that covers AL and NL east. A “west” that covers AL and NL west and so on.

Thank you
