Does somebody know where will be held? Why have they taken so long to announce it? As far as I know, the host of next competition is always announced formally at the closing ceremony, but this wasn't the case at Beijing 2018.

Has this happened before? I am just asking out of curiosity :)

Update

There hasn't been an official announcement, but Bill Poucher said (kinda) that it will be held on Porto!

You can read his "announcement" here

Second update

ICPC has made an official announcement on ICPCNews! You can see the facebook post here

Yay!
