This is great! Personally, I love super-adventures and mini-campaigns. Couldn't be better timing either! Have a few friends eager to learn my arcane hobby in the near future. By the time I wrap up the Beginner's Box introduction I have planned they should be ready to roll up their own PCs and tackle this thing!
Also, it really makes me smile that they are kicking off the new format with a dragon themed module. Very traditional and I know the guys are going to love it.
