On March 9th PST, Blizzard Entertainment announced the end date for Ranked Season 3 and also announced the schedule for 2017 Season 1 on their official website.

The current Season 3 will end on Monday, March 13, and the next 2017 Season 1 will start on the following Tuesday, March 14. Players who have completed their ten placement matches will receive portraits corresponding to their leagues as well as additional rewards such as gold and mounts - according to the highest league reached within the season.

For the upcoming 2017 Season 1, most major ranked adjustments from last season will carry over such as Hero League for solo queue and Team League for duo, trio, and 5-man team queues. The post mentions that the dev team is working to address the issues with long queue time and lower quality matches resulting from the disparity of players between duos and trios.

2017 Season 1 will last approximately three months from March 14 to June 13, and more information about the seasonal mounts will be revealed in the coming weeks.
