You make some excellent points about a 3e Taladas project, Big Mac. I'll think about it.
I should probably explain what I had in mind. The core of Dragonlance is Ansalon, and the War of the Lance. This backdrop was designed around AD&D principles, and it shows. DL worked really well in 3e as well. However, the core of Dragonlance doesn't work quite as well with 4e. It's wholly doable, but there are hurdles to overcome.
Taladas, on the other hand, may be even better suited for 4e. And as I got to thinking about the second continent of Krynn, it occurs to me that maybe Taladas needs re-envisioning to make it more 4e-friendly and more DL-friendly. This would not be "your daddy's Taladas." This would be something new.
So I quickly found places for some of the races, some of which may not work on Ansalon, but would on Taladas. Tieflings are a natural fit for he nation of Thenol.
I also looked at new ways to envision High Sorcery, such as with the Witches of Taladas
I have to admit, the 5e announcement has cut down my enthusiasm for 4e projects. I have also been looking at Pathfinder more lately too.
