Just finished reading the Master Atlas V4. Last time I read the atlas was when I got the box set back around 91. Went through my SW books and discovered I have a mint condition copy of Haalkitaine and wondered briefly about selling it for absurd sums of money, but ended up putting it back on the shelf. My old ICE books are getting carried to the grave along with me.
So to reach back to the start of this thread, I would add in a vote for Thuul, Lost Tech sounds good, and even though I know it's not going to happen The Grand Campaign.
I really enjoyed reading the timeline, you've clearly put a lot of thought into this over the last few decades. There are some stories there I would really like to see fleshed out or expanded on. Ondoval's quest for the Shadowstone, and ultimate recovery of it, must be a tale in and of itself, and one worth telling. I'd like to know what the future holds for SW.
One thing that was mentioned was the possibility of doing a panel on the future of SW at Gencon. That's something worth doing even if that doesn't happen at Gencon. You could always use google hangouts or a similar platform to conduct that sort of panel at any time. Doesn't really need anything fancy either, it's kind of amazing what you can do with a simple laptop camera and microphone.
