The post didn’t go into great detail to avoid spoiling future content previews that will be posted prior to the patch. No official date has been set yet aside from the vague “coming soon” statement that we get from most developers, but the post indicates that it will be at least a few weeks given that the team plans to release content previews over that time. Stay tuned and we’ll update you when we have more.
