Going WAYYYYY back to when the lists first popped up:
3-3/4" Jedi Council Scene I Yoda, Qui-Gon Jinn, Adi Mundi (March 2004)
3-3/4" Jedi Council Scene II Obi Wan, Plo Kloon, Ickath (May 2004)
3-3/4" Jedi Council Scene III Shaak Ti, Chema, Sta Sta (July 2004)
3-3/4" Jedi Council Scene IV Anakin, Sae Sae, Adegalia (September 2004)
Obviously, the dates are wrong, but they are coming out.
For #2, the de-coders were right and "Ickath" does equal Eeth Koth.
For #4, from the picture of the whole set, I'd still have to go with the seated figure in the picture being Adi Gallia, while the Standing figure in Set #3 is a Stass Allie rehashed out of the Ep1 Adi figure.
In set #3, Hasbro will probably give us an Ep1 Adi and just call her Stass Alliee with no changes at all.
I expect nothing more from the Big H in these days of OTC repack madness. The picture of the cloak seems to strengthen that guess.
So, I guess the debate then will be whether "Chema" is Coleman Trebor or Agen Kolar. Hmmm... from the picture, he looks too small to be Coleman, but I'm not sure. It sure would be a lot cheaper for Hasbro to just pack out another seated Eeth Koth and renanme him Agen.
Since this is the "Era of Cheapness" aka The "Anti-PotJ", I will fall in line with those who think it's Agen Kolar, simply because that is the cheapest option for Hasbro, and that seems to be the popular choice for them lately...
OTC = The anti-PotJ
