As for what they are waiting for, they probably don't want to release all of the major armored figures (Vader, Stormtroopers, Boba Fett) too close together. It makes it harder for people to afford them, and from their point of view the longer they can draw out the line by making people wait for the major characters, the better.
That too.
I do have the Medicom Fett, and he is awesome, but he is just too short to display with my more abundant SS figures. Clone Troopers and Imperial Guards go with SS fine, but Vader and Fett just don't fit as cool as they are. Some guy in the UK is getting my Fett Vader and Luke since I can't stand the size thing. More money for SS and Hot Toys stuff for me.
That PF Fett was nice too, but sold it without any companion pieces too. My heart is just set on a 1/6 Jedi version Fett to go with my growing Jabba Throne room set which began with this custom job and will continue with the Carbonite Han...

Gentle Giant Leia removed from base and de-resin-skirted and given the chain off of the Kotobukiya Leia.



So far I have everything related to this scene that Sideshow has made in 1/6. Really want Fett though. He would be the first good 1/6 Jedi version. Medicom and Marmit are both Empire (nothing wrong with that BTW).
