The end of Overwatch Season 3 is right around the corner according to Jeff Kaplan Overwatch’s game director.
When asked the end date of the current Season, Kaplan responded
We’re working on a blog right now. We’ll let you know ASAP the exact date of the season end as well as changes coming for Season 4.
Usually, seasons end one week before the start of the month — so roughly expect the same here.
If you haven’t played Competitive yet, you still have time to play your 10 placement matches which will award you the Player Icon, Spray and Competitive Points even if you don’t have time to play more matches.
That comment would suggest that the end of Overwatch Season 3 would land around the 21st February.
Overwatch is available now for PC, PlayStation 4 and Xbox One.
