Hello all
Happy New Year!
We just wanted to provide a quick update on D2R and D3 timing for upcoming seasons and updates as we have seen a plethora of questions regarding timing for these.
For D2R, we are expecting ladder reset for S3 to begin sometime in mid-February. We will share more specifics on the date with the community in the coming weeks.
For D3, players can expect PTR for the next update to come toward the tail end of January. We will have notes that will be available on our blog a little prior to that.
Hope this offers a bit more clarity and helps with timing and scheduling for those wanting to jump in right at the start.
