TOPIC: Silver ship passage array

I'm sorry if this was mentioned somewhere, but I hadn't seen it.
I know that the Silver Ship Passage Mirthwood is required for a special 12-minute mini-event at Ring Con.

But we now also have Outpost Nil, Pemberton, and Melonbrandt. Has there been any notes or declarations about what these are for? Each their own 12-minute thing at Ring Con? Or save the next one for a big event in 2028?

I see several on Trent's site and I'm tempted to sell some I have in surplus (my kids and I likely won't use all 12 Mirthwood tokens at Ring Con). My suspicion is that we still know nothing about any of these other 3, but I was curious if there was an announcement I just hadn't seen.
Thanks!
David

I seem to recall in a True Dungeon Talk w/ Trent, that this question was asked and Jeff said the other tokens would most likely be used at Ring Con, but nothing else has been said.
