Hi ceryxp,
We are targeting 6.3.1 for next week. When we finalize details, we will share them. I've been reading your and others' feedback on announcing when patches will be launched. There is a lot that goes into the messaging surrounding when a patch goes live, so we take more care in the timing of posting that info. However, I also want to say that we will be more mindful of giving a general timeline when possible.
Secondly, regarding the vendors for Galactic Seasons:
Jaleit Nall will always be available regardless of the season being active or not. Her inventory will continually cycle through the same rotation as noted in the David's post. Once Group D is done, the rotation will cycle back to Group A.
Ki'at Thavo will have Season 1 items until Season 2 starts, then his Season 1 items will be removed and replaced with Season 2 items.
David's post will be updated to reflect this info.
