Wikimedia Hackathon 2020 will happen in Tirana, Albania from May 9th 2019 until May 11th 2019. Here is the Meta page for the event: https://www.mediawiki.org/wiki/Wikimedia_Hackathon_2020
So far, there is not much information to share as we are in the early stages of organizing it but I will be posting here all the important updates as months pass by. Also, keep an eye at the Meta page.
See you in Tirana in May 2020!
