Summary of stuff from Watchpoint 2020. A lot of this is known, but it's good to have a summary anyway
Two regions 4 divisions, each has five teams.
All games are homestands next year. Matches only run on Saturday and Sunday, starting at local time
No more stage playoffs, there will only be a mid-season tournament during the all star break and the grand finals
Grand finals format the same as last year, last chance play-ins and double elimination bracket
All matches are first to 3. No more 4-0s.
The maps will be in a different order
Limited map pools will exist but Control will always have all 5 maps in the pool.
Pretty much confirmed that next season will be all Overwatch 1 (No Push)
Edit: Wow they're doing live Q&A here.
