Not yet.
For those of you who are new or are otherwise unaware, we typically announce the end of a Season at least two weeks prior to the end of said Season. Before that, there will be a preview for the next Season both in blog form and in the form of a one-week PTR for testing.
I don’t have an ETA to provide for when that will be arriving for 18, but I’ll leave it as something I’m actively working on.
