They also answered my question:
A few more questions about General Kenobi: 1) Is Obi-Wan going to come with a Clone Trooper helmet? 2) Is there any cloth being used in the armor itself (the black areas)? 3) What kind of sticker shock can we expect to see with Obi-Wan during Friday’s PPO?
1) General Kenobi will not come with a helmet. 2) There is a brown cloth undersuit under the armor. (Stay tuned to our Production Blog for an entry that will show the armor pieces!) On that note, please understand that the armored pieces and undersuit are not meant to be removed from this figure. Attempting to remove the armor, especially the torso pieces, will cause damage, and you’ll have to invest in some glue to make repairs! 3
) We believe that Star Wars collectors will find the price very fair, and reflects the artistry and development put into the piece, while simultaneously maintaining a very reasonable price point in the market.
Basically, Obi-Wan is going to be expensive
Sucks about no helmet though. Was HIS undersuit brown in the cartoon? I don't know why there would be a brown undersuit instead of black otherwise.
