Jeff actually presented that idea as an exclusive (more VOTC figures) to the guys at Target last fall. I think Hasbro and retailers know how well those things did, perhaps we will see them in future. One can hope at least.
Here's a list of possible Holo Figures I made last week:
Darth Maul Episode I Talking to Nute and Rune
This one actually got made, Scott. It's the WalMart exclusive holographic Darth Maul that was offered along with the holo Qui-Gon Jinn. It may not have been part of the basic figure line, but it is Darth Maul exactly as he appeared as a hologram in TPM.
Holo versions of Ki-Adi Mundi and Plo Koon would be welcome in my book. Especially versions that can sit in the Jedi Council chairs. As things stand now, the holo Yoda that was offered cannot sit in his Council seat, so I'd like to see that, too.
